6/10 Everything is nicely done, especially the background, the combination is what ruins it. The render aren't really a part of the sig. There's too much Sonic, who's also a little too big.
Glitch, I'm gonna give you 5/10 because its a cool car but it looks like you just put letters on top of a pic and thats it.
Both are nice. I feel the text needs work though. 8 for both | V Rotates, please say waht sig you are rating!!!
