Yes, when I do my own signatures I will commonly just go with things that I already like instead of making new things.
I don't usually have the time to design completely original content, however when I make things for RRR (like banners/awards/etc.) they are usually completely original.
If I had more time, I would make loads of graphics just for the sake of it because it's one of the only things that I consider myself to be good at in visual art. D=
All right, you try whatever you think is best and I'll just have to wait and see.
