Looks nice, but it I'll stick to my good old Paintshop Pro (Version 6 ) for logos and buttons. Especially because I don't want text logos, I prefer image logos like my dustbin::games logo (which I'm really proud of):
They actually match up directly with Gimp's scripts. I'm guessing the site runs Gimp internally to render everything.
The logo looks nice! It all really depends on one's artistic talents. The link I provided is simply a solution for the more artistically impaired among us
