This is an interesting shot, with some very nice shapes. It has a grungy feel to it, yet that conflicts with the soft-light editing you've done to it. Forgive me if I say this, but would it be better for you to explain why you took this picture and made it look this way? In my opinion, abstracts that have posed subjects shouldn't be taken 'as is', and must have a certain interpretation to it. Perhaps you may want to share your interpretation of your photo so we can better understand it?
Still, as this is photography, we can't avoid the technical stuff. The composition of the picture seems to suggest a frame for the main subject, but there are too many empty spaces where this 'subject' should be. As foxtwo mentioned, you may want to have a background that can fill up the negative spaces in the picture.
I can't wait to hear your interpretation of this! It'll help me appreciate your recent works better.
