Why haven't I heard of this guy before??!
Almost all his work uses dramatic light sources and has complementary color palettes playing against each other to make you stop and look.
His digital paintings are perfect for fantasy and sci-fi inspiration... ...(though be aware he's illustrating book covers as well as producing original works)
and his photography is an urban fantasy author's dream, with some dramatic landscapes thrown in for good measure. There are stories in all of his pictures.
I can't make up my mind if I prefer this guy's illustration or photography.Luckily I don't have to choose!
NOTE: Be prepared to be at his online gallery for a while - he's a prolific artist!
