Sketching in good ole photoshop

So anyways I've been watching a few gnomon dvd's lately, which are unbelievable. I picked up a few tips here and there and thought I would give them a try. This is a work in progress, alot left to finalize it and colour it up. It's some kind of creature but based on a prior sketch i did. With school getting crazy this may be my last post till summer. Enjoy!
