if only if only...

Love the mood, the only thing that gets me is the BG I think the hands/arms are stretched a bit much, they look like you just grabbed the smudge tool and said "screw it." I would have like to have seen a stronger DOF so they fall further out of focus, or more substance to their mids. Also, if you going to put the Ying Yang in there, it should be placed in a position where it can be the light source, it's a little weird for it to just hand in the middle of the frame when your light is coming from the left. Over all good job. Great use of color filters.

You have the reflective qualities, but now you need to adjust the curve. The image is flat, for this to look like chrome you need high contrast between you shadows and highlights. With chrome, highlights define the structure, so make some adjustments and place highlights on key areas to make this more 3D, more living chrome. Finally just give a hint of greyscale to the image without compromising the reflection.

It looks good, but be consistent, the reflection can't be black and white when the foreground isn't.

I would have like to see some texture placed on the "floor" of the gradient
