*nods* Good work pal, I really like the coloring and also the background. :)

I actually like this a lot. The relaxed posture with his hands crossed and eyes closed as he gives a yawn, captures a very serene moment.
I also like his overall look. The muscular build and thick neck beautifully compliment the calm of his mood.

Of course, I always enjoy a nice maw shot, and I love how you can make out his gullet within his frosty breath. And finally, despite the labeling as 'macro', I love how barren the terrain is, making it questionable as to his actual size; leaving it up to the viewer to wonder if he's huge, lying across snow-covered mountains, or average-sized and simply atop a mound of snow and ice.

Very nice job on this one.
