I personally do not mind the look of it aside from the lower left lighting that was mentioned before. The sun glare circle things and such are nice, though they give me the feel that it should be animated. I think it could look pretty cool if it started with the standard title on white background, giving off the normal final fantasy feel, and then had the black and white background fade in with the light effect casting across it creating the glare circles in the process and giving the feel that it is not just another copy. It would be a lot more extra work, but it sounds interesting anyway. As for the title, when you release it, the full name should be written out. FF:CC actually has Final Fantasy Crisis Core written out fully in the title. You could always try a clearer font as well that does not lead to misunderstandings between letters.
I have no issues with fan games. I do not play them, but I am not going to get upset if I see a lot of them getting made.
