It's so exciting to see an interior shot of this building--and done so artistically, as well! Hope to find more great shots of this building in your portfolio once the challenge closes. Luck.
It's hard to say how I feel here, I agree with your idea, and I like the light/shadow technique, but the architecture comes off here as busy and the DOF is a little shallower than I would like. Maybe if you deepened it to bring the whole image into focus the floor area could balance the architecture more?
The architecture is pretty interesting, but i think the quality of this shot could be a bit better. Good perspective. I like the contrast of the colors on the chairs/ floor to the blue of the pattern.
Very cool shadow effects there. Unfortunately, the patterns kinda hurt my eyes if I look too long. Too bad about the support beam in the shot. Good color and lighting.
