I really like all of your artwork. You combine careful line art with subtle shading, and ojn top of that you have a good understanding of the anatomy of dinosaurs. The only suggestion I can make is that dromaeosaurids such as Deinonychus were probably covered from head to tail with primitive feathers. If your character is specifically an unfeathered Deinonychus, that's OK, but that's not the way they really looked.

I love your dinosaurs! I also love your horses! beautiful! The source of light is really good. Whcu program did you use to colour this?

It's so nice. You should read raptor. Except you might feel sorry for the Raptors by Paul Zindel... when most of them drown you might feel bad... >< But then, you would actualy feel for them. I just panic and stare at my closet all the time now. Was that a rapter?! No, just my cat. XD
