I find it really hard to imagine dinosaurs as if they were human; but, those drawings are imaginative. Much better than what I could come up with. I can only imagine what the Land Before Time characters would look like if they were anthropomorphic and wear clothing.
I like how Petrie is shown wearing glasses and how Ducky is a blonde. Cera as a redhead could work and same with Littlefoot having the same hair as his parents because his dino form is brown.
Anyway, keep it up with the drawings, these are pretty good.
