So-So.
Looks better then your last one, no doubt. Just a 3 things though...
1. Looks like you copyed alot of the starting animations for the action scenes. Please, dont do the whole " I didnt trace it, but im glad it looks like i did : ) Im flattered" thing. Some of those, if not traced, were definatley influenced/looked at from the Sonic X series. Specifically Sonic doing certain actions. The 2 robots and robotnik no doubt were. And no, im not gonna look for proof just to prove this statement.
2. Tails looked...weird.
3. Sonic X Style D: You should do the Sonic Adventure 2 style, looks much more "mature" then the sonic x style. Most of Sonic X's style looks pretty bad, especially when characters face front. Might just be my opinion, but i've seen a couple of people who agree.
Im not trying to be mean or anything, but it certainly looks like some of the animations were copyed. Maybe try and put your own thing on it instead of trying to make it look like Sonic X. Just my opinion :) Keep up the good work.
