I was bored an experimented quite a bit. ~with text~ ~without text~ {fixed the quality of Wrath render... sorta}
Theres not enough in the picture. Try putting a transmutation circle on the side. That might look good.
It's alright. The only thing, though, is the white lines on the render and the low-quality of it makes the whole sig look sloppy. Not only that, but the backround is plain and is lacking something. Maybe you should try some nice brushes on it and maybe sharpening up the sig a little bit. But, good effort.
I like the layout and the color of the signature. The picture seems to be a little fuzzy to me... everything else is perfectly fine with me! :D
I tried to fix the quality of his face and stuff. >> It was hard, considering the original picture I used was suckish, but eh, it looks a little better, I guess. ~original pic~ http://i335.photobucket.com/albums/m457/fma-wrath/Wrath_in_land.png
I suggest you use renders and stocks from professionals, you know? You may not want to do it on your own just yet.
Hmmm. Find more things to put into it! Just one pic and tesxt isn't enough! Get more pics from FMA like that symbol that kills the homonculus! Or Wrath in his Wrath mode. XDDD But it's good. Nice job! ^^
Never, ever use low quality pictures. I can guarantee that you will never make nice signatures with low quality pictures, and rendering in Gimp is pretty much a no. If you ever need a render done, you should request in the Shop section. Or PM me; I'd be happy to (although I'm not very good).
