U asked me to comment on it..Ok big improvement Slash..
but here are my comments..
1-Try to make sig not with the same style (having the bar text thing behind the text).
2- IMO, Bowser would look better if you increase the size of that image abit.
3- I like the colors you used in the bkg. very well done.
4- Try not to use the glow effect on the text on that sig, would look better without that glow. Better to add shadow instead imo, coz the text doesnt seem to fit the overall style of the sig.
Good job Slash.. improved alot man.
