Ah, I've been waiting to share this image!
This was shot back in July as part of my 365 Days (Photo-of-the-Day) project and as part of a "minimalist photography" project on another site.
Getting behind on my comments.
I like the color and contrasts that you have set up in this image. The red-orange is a great and seldom used color choice. Bold of you to use it. The only comment I have beyond praise is that it seems a bit cramped in the lower left. The pool of orange seems trapped by the phone. One of my design teachers told us to make elements look intentional. The interpretation here would be to give more breathing room and let the orange flow freely.
