Just did a Jon Jones Sig..
It took me some time to work with the original render (it was a difficult one - a screen shot, not the best quality), plus i really wanted to add some fire in the sig...took me some time until i found something interesting.
I have them in a pack of two...one has different lighting and saturation.
PS: by mistake i've deleted the original sig in .psd format
so i'll take you sugestions into considerations and work on them after (id you have any!
