As much as I'd like to say this without sounding
mean, I don't think I can. Don't take this the wrong way...
It's a recolor. I'd say start over completely. It's just Shadow, in different colors. Alter the quills, give him a unique flare! I, making dozens of characters, know how important this is. My older characters were all recolors, so I know what it's like. Just keep trying.
EDITAfter seeing this, I say it's an improvement, but, to me, it just looks like Shadow with Amy's hair. Adding more streaks was nice, but the colors clash. Badly. It still needs a bit more. But it's still an improvement.
Sorry. Years of sprite concrit does this to you.
