I dont like it,
- To plain
- I dont think it is the greatest cut pic ever tbh
- background is nothing really, green & grey dont really go togethor imo
- Font is pretty good
Overall just too plain, all you have done is go to render, clouds green & grey, typed Live Fast... etc, and stuck the cena psd on. You need to put more time & effort into your sigs, its not a race. Try maybe a gaussasian blur on cena and then ctrl+shift+f and select soft light or overlay, but dont do that bg ever again imo.
