Can't believe how long it's been since I've made a sig (maybe a year or two). I literally just whipped this up and whoa did I feel a bit rusty. I almost forgot what I was doing. Anyways, here's my submission:
Character: Yuffie
Video Game: Fanal Fantasy VII
Yes, I'm still making my sigs 370x120. I just can't seem to let go of that size.
Not sure if it's needed, but here is the source image for the render I used: http://bakarenders.com/renders/albums/userpics/26648/32_render_YuffieFF7AC.png
