CS3 quick layer masking, and dodge/burn to background layer make the 'implant' process looks as natural as possible (not the best result I guess...). The "TOMASZ" vector 3D graphic was done in U-Lead 3D
Just a little tweak on the level, Erick. Not the best result I believe. But the idea of light adjustment was there. Hope you find it useful.
