Ok open the Gimp and get your background wich should be something like 350x120 pixels...You then click on dialogues and then go on brushes...You should find a brush called the spark brush brush with that till you've got a background like this.










Then you select another brush that goes by the name of vine brush and brush round with that until it looks a bit like this











I think this would look good for a Kung Lao sig......



It looks nice when you colourise it as well.




Here is a very simple brush thing as you will only need one brush throughout...


In your brushes their should be a brush called galaxy AP


Just brush around with that until you get a background like this









Then you colourise it make it a nice yellowy colour like so...









If you want to make this look better go to filters and then distorts...Then ripple.


You should get something like this...








If you don't like this you can experiment with other distorts...



Another one is simply just get your base background brush around with the pencil sketch brush then you get something like this...









This looks extremely crap but go on filters distorts then mosaic tiles to get a really cartoony background...








This looks good for a Reptile sprite sig.....



All from me
