Since you're new at gimp, I sujest you take a begginers tutorial. YOur sig really has nothing fantastic about it. PLay with gimp and try blending in the stock.
Blending...in...the stock.....? Hows i do that? Lol, i read quite alot of tutorials..... But brushing and clouds and saturation and text and...stuff like that is really all i know how to do. Oh, and layers. :D
Iunno if this is what you meant, but I did the thing where you make a new layer and paste a whole bunch of what your layer is, and then you do the blur thing... bla bla bla.. this is what i came out with.
