I have been following Andy Kehoe's work for a while now. I came across him from browsing the Tiny Showcase archives. (I say this as if he's some undiscovered artist, but I'm guessing he's probably doing allright for himself actually.)
I really love the colours he uses and the way he often contrasts his background with the subjects. He always seems to paint skies brilliantly too. Oh oh oh and I love the way he draws spirits and ghosts aswell - perfect.
