This is my first pic using GIMP. tell me what think Mitsurugi is from the soul calibur series btw. if u want the render for him just google mitsurugi HOW DO U MAKE NEW BACKGROUNDS?????
I would agree with hellclown. If you where gunna use that as a sig, it should be a lot smaller and the background less busy. The font and render are good but I don't think pink goes well with it. Keep trying ps: yay I'm back from holiday. Oh damn, 51 emails...
The render doesn't blend. Colors don't blend. And the render is also too dark. The background is horrible. But considering its your first, not bad.
Not horrible for your first time using the infamous GIMP program, but you will need to practice a lot before making quality images. Tips for the future: Avoid repetitive (repeating) images in the background or as the background. Use a font that isn't accidentally pixelly. Find a color/contrast scheme and stick with it. Only rainbows look good with every color on the color wheel. 0.8 out of 5 stars
Regarding the green background and purple text, use this color scheme generator to help you with colors. Choose the main color you want to work with and it will choose some matching off-colors for you.
Um, large sig is large? Seems a bit above the 500x200 limit. Render doesn't blend, no flow, basically what everyone else said.
