I think this image has potential but it is incomplete. Try cropping the image down to improve the composition by moving the surfer away from the center. I would also include just a little bit more variation in color. You should also find a way to deal with the lower corners of the image. They are too square and un-dealt-with.

I like the look but I don't see how it falls into photo manipulation, it looks more like a vector image
