Holy... Shit. I'm nothing if not sparing with my praise, but this is amazing.
Two suggestions (not criticism, I'd just love to see this done): 1. Manually brush out the more obviously liquefied (or whatever tool you used) areas 2. Cast the diffuse colored light from the brighter foreground objects to the surrounding floor
With that done, I'd say this is one of my all time favorite pieces, old masters included.
Good Lord. I can see why you only bothered with one word in the comments- it must have took everything to barf this up XD. Not that it's bad :3. It's that good type of barf. The kind with bright lights and small, very well done details ^^.
