Excellent! Very excellent! I love the design. Terrific details and pose as well. I would like to have the head stand out a little more, right now it blends in a little too much with the rest of the body.
I really like this dragon's design. It's not too complicated, but stands out in all the right places; an interesting set of horns, tough-looking armor of scales, folds in hide where the skin is unprotected and a lovely choice of color as well. I do have a soft spot for wyverns
Actually my original idea was to draw a real dragon instead of a wyvern, calling Wyvern just because I can't think of a better name. Glad you like it. By the way, your work are awesome too. ^v^
