Its rather small.. but it's way better then most of the sigs on this forum.
Nearly every sig on this forum is shit graphiclly..
some tips:
- Get lost of the inner shadow on the border.. doesnt look good.
- Work more on your background.. its just plain red with some white brushes.
- Use an other font and make the text stand out more.. check
http://www.1001fonts.com for new fonts. some really nice ones on there
