Blac glass shelves for iPhone

An attempt to a balck glass shelves wallpaper for iPhone.
Version 1.1

Software:
- Sketchup for the model.
- Kerkythea rendering.
- Photoshop for the rest
- iPhone for the screenshot

And i know i'm going against the Apple perspective, but i'm trying some different things... i'll promise i'll stop to experiment on perspective when i'll find out i'm completely wrong

Let me know what you think about!
