t rex sketch (new stuff on page 3)

[Zelan]

Thought I would share this T rex sketch I did:



It looks a little bit like its pasted on because my scanner sucks and I had to enhance the image which also made some specks/smudges a lot more visible, so I went into paint and covered it all in white.

I mostly just doodled in the past but I've been trying to learn how to sketch better, I'm not too good at shading so if it looks off that's why.

Any comments, feedback, criticism would be welcome. 

updated with bigger feet:

Looks very good, no obvious errors that I can see I just noticed, it sort of matches your avatar.

So it does, I didn't even really think about it until you pointed it out lol.

It does look quite nice. Well done !

Hmmm .... it looks to me like the head is a little too large and the feet too small for the body ... the feet are the bigger of the two problems in my eyes ... some specimens like "Stan" had heads much larger in proportion to the body than your average TRex so that doesn't bother me so much .... but the feet need to be larger ... TRex had exceptionally large feet for a theropod of its size ... theories are that it lived in a partly marshy environment where big pads would give it more stability on softer ground ...

... the legs also look too short - remember that TRex had longer legs than, say, Giganotosaurus or Spinosaurus ...

... suggestion:  erase everything below the knees, consult some skeletal photos (don't just rely on other people's drawings, but analyze some skeleton mounts yourself), and then lengthen the lower leg and enlarge the feet - significantly...

P.S.  As great a model as Krentz's 1/40 Shapeways TRex is, it also has feet that are too small for the body ... so its a common mistake, even made by some of the best artists around ...

Sue:

There's no modern animals that I know of which show their fenestrae. 
You might want to smooth those over. You might also show the ear hole.

Sue:

Maybe its just how big her body is proportionally but Sue's feet look small in that picture (at least to me).

Regardless, yeah the feet were a tad small and the head is too big. I updated the feet and legs slightly but it's too much trouble to redo the head, might as well do a new sketch. I've also tried to draw it without fenestrae in the past and I can't seem to make it look good and natural, it just ends up looking even weirder. I also did draw an ear hole, it's at the back of the skull but I really have no idea if it's in the correct spot.

Out of curiousity, what animal alive now does have antorbital fenestrae? I did a quick search and can't seem to find any. Crocodiles and alligators apparently lost theirs and birds don't seem to have them either in their beaks.

Appreciate all the feedback so far.

[Blade-of-the-Moon]

You could just do scales or boney ridges outlining the fenestrae. I've often had trouble as to what extent to show them. It seems many artists still show them in one way or the other but not deeply sunken in any more.

This really depends on the angle and lighting condition when you are viewing the animal (for example see http://www.arkive.org/gharial/gavialis-gangeticus/image-G114512.html with jaw muscles bulge out, http://www.arkive.org/gharial/gavialis-gangeticus/image-G114505.html with jaw muscles sunken in).

I really like that Tyrannosaurus rex picture! 
No big errors,but,have you considered making it feathered? 

[Jetoar]

Congratulations for you draws friend  !

It is not necessarily wrong to draw/indicate skull openings, it still is a possibility... (see below):

This is a skull of a tuatara; notice the postorbital and superior temporal openings?



Here are some "flesh out" images of the animal...









From these pictures, it really isn't that hard to work out rough outlines of these openings.

To answer your second question; the simple answer is "no". We don't have any modern example of animal that has an antorbital opening. Crocodilians have lost them as their skulls become flattened... and as for birds, since their lacrimal bars are reduced; they also lack a complete antorbital opening.

that's a very good T. rex, i like it a lot. kudos.

[fleshanthos]

I would look at actual Theropods rather than their cousins.
We made the mistake of Dino lips being like this Tuatara - in fact the entire head copypaste 100 years ago up into the 80's and look how stupid that was - I groan when I look at Triceratops in my kid books.

I would be very dam careful about showing off fenestrae. Muscles bulging out of them - ya. Depressions? nope.

But I suppose it is up to the particular artist - for now.

Now that really depends on the jaw action. If the animal is opening its jaw then the jaw closing muscle (like the adductor mandibulae externus which can be view from the posterior opening) would be stretched and would not have been bulge out (or often the surface of this opening would become almost flat) as much as when the jaw is closed.



compare this to some of the previous images. The posterior orbital area appears to be forming a depression. Of course this isn't strictly about tuatara; it is just how jaw muscles operates (another example can be seen from an earlier post http://www.arkive.org/gharial/gavialis-gangeticus/image-G114505.html, in this image it clearly demonstrates that depressions could possibly occur on these openings). Or this example, though this animal lacks the lower bony strut to complete the postorbital but the principles are the same.

[Zelan]

This picture also shows a very obvious depression http://www.arkive.org/komodo-dragon/varanus-komodoensis/image-G111686.html. It does seem to have a lot to do with lighting and angle though.

As far as my sketch goes I just mostly outlined the fenestrae, I wasn't trying to make it seem like it's super depressed though I can see that it does kinda look that way. Something to tinker with until I get the right look in the future.

Are you referring to the class Aves? All modern birds lack conplete fenestrae so how would you propose to observe this feature on an "actual" theropod?
