Text looks much better than how you did it before. Try using different things like that in sigs to come. Stocks need more blending. I could be more picky but for now it's okay. Definitely your best so far.
Well, here's some advice I have to give: I think the left side blends into the background more than the right, so I suggest shortening the left side to take out the blend, or blend the right side more by making the sig bigger or blending out some of Xigbar. The characters on the edges of the sig don't look that badly seperated, although the left side could do some work, but the ones in the middle seem a bit overlapped and mixed in. One more thing: remember height ratio of the characters. Like Roxas, who's shorter than the other members. Although, you don't have to care about the height ratio if you made them purposely like that. I'm sorry if I was harsh in any way. I was just trying to find any little problem I could, because I want to give some good advice to you! So really, you did rather well! It certainly isn't the "worst sig ever." It's nice to see a signature with all the Organization XIII members in it. It's very hard to contain them all in a small area; I sure wouldn't want to take on the task:blink:... so mistakes are understandable.
