This is an old avatar of mine. Sadly, I have lost the .xcf file for it so I don't remember what exactly I had done to it. I do remember that I had darkened the graphic and I think I had blurred the edges of the character in the graphic, as well as adding in the text. The other half of the set is this:
With this, I had started off with a white background. I put the pics of the character in a different layer. I put in the text before the character, then adjusting the opacity of the character layer so you could see the text through the character. I then added in a layer that was completely black and adjusted the opacity on that to make it dark like that. I had tried the brightness adjuster first, but I just couldn't get the effect I wanted from that. Of course, the graphic turned out a little darker then I wanted it too in the end. It was quite a learning experience for me since I didn't know much about the whole transparency topic. Oh and the lost touch was putting in a gradient.
Any feedback is appreciated.
