I'm drawn to the first one. Love the simple contrast between the dark and light. I might crop off the bottom third, the really light part. Fun stuff...more, more!!
I like #1 the best because it feels very serene to me. The third one has rich amber tones which are warm and lovely, like smooth chocolate and gold. All three are nice.
#2 looked like green tea, but I don't get very excited by green tea.
#1 looks like a sensuous abstract - has curves, has fluidity, has some defined shape without defining "a" shape. This one has my vote as the most interesting one, although they all are very attractive.
