I like it, but it still needs something. Maybe more color, or a little shading on the "rocks". I would try making the lips out of the same shapes as the rest, too. It just needs a little bit more "oomph"
This is a good idea, and different enough from everything else to stand out. See what you can do with it!
A lot of work, I respect this. But this face has no nose. A man without nose is like a warrior without spade, like a king without crown or like a dog without tail. Like a poem without words... I have more to say but my English don't help me to express all the feelings. So much sadness in his eyes! Oh! Hope this drawing will sell here on DT, but for sure will sell more expensive after artist's death!
