The Wiki Portraits are a bit fugly when blown up that large.
A bit of editing could make them look a lot better
I got a bit of glow and parts that I didn't clean right left yet AND I over messed up on the cut since I did it quickly(dunno if it is easy to spot or not though). In addition I didn't play with the enlarging settings much, I could probably get a better result with a bit of effort(a couple minute hack job really doesn't give you much time to fiddle). Currently it is a bit pixel-y in parts. I probably had the definition settings too high.
Anyhow, before I can do anything I first have to figure out how images and wiki work. I don't normally edit Wiki's and when I do I have never used images before. If I scare up some free time that I want to spend playing with photoshop I'll try to do some of the others as well if ya'll like. After all I can't do much else for the wiki at the time being.
