Concept: I've based my wallpaper on my signature, created for the 21st signature challenge:

Number of Layers: 15.

Time of composition: 2 hours.

Work Details: I've blended the two scans, erasing the unneccesary parts and clean them with a overlayed shade of the same scans. After that I've added (with pen-tool) some parts of the deco and added light effects.
