Awesome
Well I guess for once Sonic finally snapped but admitted he need someone to help him to do something which was to live and get off the spike that impaled him. I think while he was telling us how he went so fast he probably should have watched where he was going. It is why you can't drive a car and have your eyes wander elsewhere unless you want to be in a crash and get fatal wounds.
The animation was very nice and it looked like a mix of being drawn by hand as well being drawn on the computer at the same time as well. The graphic vomiting and blood was also very nicely drawn; as was the backgrounds and other items drawn up with Sonic.
I though the voice acting was fairly nice and well done so nice work there. I like how Sonic finally explodes and tells Tails how whiny and useless he is but then he apologizes stating he is his best friend and almost always there when he needs help defeating Eggman and his stupid robots.
I found the choice in audio to be very well chosen and I appreciate the credits too be funny as the mirror the annoyances of modern day television shows as well where you can't appreciate the credits and music and instead get annoyed with ads for other shows that the viewer probably does not care about either.
I would have to say that overall you did an excellent job with this. The blood, guts, and vomit were nice and the credits mirror that of modern day shows. Great piece of work. Looking forward to more in the future.
