it looks really cool in thumbnail, but when its blown up real big it's almost like an impressionist painting. cool effect, but if you're wanting to get better, maybe you should try and keep working on that same painting until it looks more like a completed realism painting. great job though, keep it up!
thanks and yeah its not so much about realism, its about finding and creating the right brushes, its so hard to create a "rocky" picture, maybe I should start with matte paintings
