Looking cool steve, I really like the head you've got there. All it needs is some tweaking on the snout/lower mouth area and it'll be spot on. Nice start on the front of the body too.
I should get my polar bear head out and finish the body so they could have a fight

starjsjswars - dont know if you do life drawing but in that its better to start with the head so you can always re-reference proportions back to it as things develop - it saves ending up with a pea sized head at the end (which I have done many times in the past)
