I like the rex in the front

His neck is a bit too thick, but excellent detail on the head!

yawn

it really needs more into it. cool but kinda lame 'coz there is nothing special 'bout it

Great drawing

Like already said, I feel the same way about the back dinosaur, to be honest he just looks rather rushed. The front one is perfect and the red background really brings out the mood of the dinosaur.

It's not that its like the back one is badly drawn. It just doesn't flow the same as the front one, causing a clash. Even if you made this as two separate pictures, I bet they both would look better than this one as a whole.

Either way, great work on the dinosaurs.

Awesome

It's great,but I don't like the look of the dinosaur in the background,you should work more on that one.
If I was you,I'd completely get rid of it,cause it doesn't have any (positive) effect on the main dinosaur (which looks like...wow) and that is the main reason I give you 9.
Thank you!
