I like the canvas texture. I think it makes a change of pace from the futuristic glossy look that most folks use for this type of image. The water and reflections are very well done. I'm not sure what the floating sphere is all about, but it draws your attention and makes you ponder.
I just have a thing for floating, reflective spheres. I'm not sure if there's a term for that particular disorder... maybe floatenreflecteresphaerophile? Yes, I'm a raving floatenreflecteresphaerophile.
