You might want to add a larger border though, this small one is great, but would look cooler if larger. Bear in mind though, adding border to all sides isn't as appealing as adding to the upper and lower sides. Adding to the left and right might look good too.

Anyway, I'm not here just to give advice :] I want a sig too!
I'm not too picky with this stuff and like to leave the art to the artist, so feel free to do as you wish. Btw, the waifu I want is Mei Plumblossom(Yukata). DMM ID and Nutaku are on my signature, ya pick on whether put both or none.
