To be honest, the 'More Like This' feature didn't really work for me yet. I tried it out more of curiosity than real need and it returned artworks from the same artist and then some stuff with similar color palettes and shapes, but I find it easier just to type keywords in the desired category and do some browsing by hand.
I feel my own head splitting apart, the force the brushes are giving is head wrenching in a very cool way. Its so abstract but part of it feels realistic which I feel comes from your great use of contrast and of course lighting.
Also this must have been quite fun, take long to edit it after you got the initial idea?
