hey i think it is great i give it a 8/10 i just think you change it to the Sora from KH2 and make black and red for more help pm me i like to deign sigs!
Yeah it goes really well with the Riku sig. Same style b/g and nearly same pic but different characters.
For one I would add a border around the whole contour of the sig (so completely around it) . I can't tell if there is one there but all you have is like a border that is like 3 px in.
Text could use some work. The font choice in fine but you could probably do more than just what you did. I would also capitalize the "d"s in Deep Dive... (that's just me tho')
The b/g is well done with the brushing and all. The colors go well with the sora pic as well. Maybe there it too much empty space on the left side tho'.
