This is one impressive-looking beast! He (if it is a he?) may not seem the most authentic, or the most ferocious (he sort of looks like an incredibly detailed Pokemon variant more than a dino), but I really like the detail. Smooth shading, and a gloss-like texture that gives his skin an alien-tone. The hazy trees provide a nice background. Atmospheric, soft... if it's meant to strike fear in the hearts of the viewer I don't really feel you're getting that across, but otherwise it's a creatively chubby interpretation of this particular breed. Baby T-Rex, maybe? If he is full-grown some points of comparison would've been good for the size to really come across. Nice work though!
