I am always impressed by truly original artists that use wild colors and composition that my mind is incapable of. But one of the best to my thinking is Alex Kanevsky, great rough brushwork, fantastic anemic color palette and intriguing compositions. I should add the point that many in this catagory are epic failures using gimmicks to disguise their lack of talent.
I found this fantastic reference from an old photo, I as usual neglected to write down any information, it may be a famous person, regardless he looks very cool. Then I used the color palette of one of Mr. Kanevsky's nice interior paintings. It's still obvious that my painting lacks the wild rough edges and loose paint strokes, but I try.
