Teeth are just a placeholder with a curve modifier. I think the front view looks very strange. Feet and hands need more work. Thoughts?
This is a good start. The obvious thing that stands out is a lack of definition on underlying structures, bones and muscles. Don’t bother with the teeth for the moment, just concentrate on getting the form correct and looking pleasing from any angle. Have you collected and referring lots of reference? skeletal photographs and images of other artists work are good to look at. When creating my trex I mainly looked at the jurassic park trex as I think that It is the best looking and most impressive interpretation. Also look at birds skeletons and muscles too and chicken feet are pretty good for reference.
I look forwards to seeing this project progress, have fun.
