Fierce beast- Raptor

I was trying out something different, I like how it turned out, however, I feel like it could be better with the line art and there the background.
This was for practice and not my current skill really, since I only wanted to try to see if I could add some details into the dinosaur skin and of course with the blood and teeth, another practice with the jaws and a few other things that I can't seem to remember?

This is not a Jurassic Park dinosaur btw, this is just an idea of my own with dinosaurs!
