Draw Box - Photo Study of a Creature

Hey everyone! I've just completed a photo study of a big cat, a panther! Considering this is the first time I've ever drawn or painted an animal, I'm pretty happy with the outcome. The challenge was given to me as a draw box master study, with an emphasis on creatures. However I decided that having no experience with animals whatsoever, I figured a photo study would be best. Check it out guys!
