Bigger would be better for this!
I really like it though, both the realization and the idea.
Its almost completely abstract. More detail higher quality may bring it back to a more literal looking image. But I think that would be a good balance between the two.
If you could get it so the light/dark ratio is a little closer to 50/50 in terms of over all space in the frame ?(but keep the current feel and over all look), then this would be extremely good.
Make it poster size and print on a metallic photo paper, or a matt art paper (to see the opposite), and it would likely be worthy of a premium frame and glass.
Yep, I like it.
