I think it looks pretty cool. Maybe if you add a layer to the BG and then fill it with either yellow or purple and then lower the opacity...that might look kinda cool.
I think it is cool like it is though, at least 8/10.
This one is awesome. Dont do anything to the BG. Work on text, and it will be sick. This is different, which makes it good as the the standard sigs we see here. Keep it up.
