Pretty cool, but looking at the mountain itself doesn't make me think "mountain", simply because I'm thrown off by the jagged edges (they're too defined and shapely, almost like shark's teeth) and the way the texture of the mountain looks. But still, it's nicely done. :3
I've done some digital paintings myself (though, I guess if drawing anything like backgrounds or people on the computer counts as that, that's all I do on the computer), but I've never really cared to share them. I tend to paint more often in real life with watercolors, anyways. xP
Keep up the good work. :3
