As a huge Jurassic Park fan, I approve of the idea. The line work, coloring, and structure are not good at all, however. Nose, eyes, and highlights are especially egregious.

That said, I can't say enough how great the idea is. I haven't looked at your other stuff, but assuming this is representative, I think if you honed your skill to a finer point and tried again this could be wall-hanging material.
