Hmm , V2 is better but the border is wayyyyyyyy to thick IMO. Also the text wants to be blended a bit better, id advise taking colours from your render for the text and then playing around with the blending changes (e.g. Overlay etc.) luminosity seems to work well. Your render is quite well done and blends quite well, you can blend it better though by pressing CTRL+click the layer. Then go select > feather (its select > modify > feather for CS4 dunno about others) and then once on feather set it to 3 px. and click ok then just click the mask button in your layers panel (the grey square with white circle in it). Ok finally... id add a C4D or 2 so it adds some depth to your sig. Good job so far though you've obviously taken a good grasp on Photoshop already and i see great sigs in your future

even if im not an expert :p
