uhhh...

this is WAAAY too short. plus you shouldnt have put advance AND battle sprites for shadow cuz you should only use one type.

Nice!!

I wonder why is shadow helping them when he just kicked sonic's ass??

Not the worst out there

You spelled "since" wrong, as it's actually "since". There were a lot of problems with this, particularly with how everything seemed so disorganized. What was good was that the sprite works weren't half bad. Everything just moved so slowly as there was not much action in the beginning. I don't know why everything seemed red with Shadow's fight with Sonic. At least it cleared up when Knuckles and Tails arrived.

It also ended too abruptly as I was expecting some credits. The font that the characters used was a bit too small. It would have been better to have the dialogue contained in a box too. You need to brush up on some stuff, as being just introduced, I can not say much for the story. I am used to sprite movies like this on the website.
