Very nice, I'm just not sure my eyes are being drawn to the purple as much as they should be :P

I like the metalic effect you have achieved, it is just a little too abstract for my taste, I am not sure what you are trying to represent (if anything). Still, thumbs up for the execution

I personally like to see more of the source image used, but this is certainly an imaginative application and well executed.

I think your masking could use some work, there are some great tutorials on masking so I would check them out. It really is one of the things you have to be good at
