First Sig: Really like this one. Only thing that bothers me is the blue outline on sephiroth's clean side; it could be a little less lighter. Second Sig: Luxord really isn't blended. I also hate the white outline. Third Sig: I hate how it's dark on the left side. Don't like how his arm cuts off inside the text. Not blended at all. No real flow.
OK 1st- As blacknumbers said, the blue outline is way too heavy. 2nd- I pretty much liked this one. 3rd- The whole background is dark.
