Friends are everything (Anniversary Idea Fail) Ed

I missed out his last anniversary so I wanted to something this year. This was my first idea, when I sketched it out, I thought it maybe wasn't as good as I thought so I just finished it as a normal piece.

There are a lot of thing I did wrong here, one of the easiest to see are Tails' shoes, that's also why I coloured all the soles black instead of grey, also the first time when inking it I had placed Sonic's right leg wrong. And when colouring I colourd his left arm blue
Oh, and there are splats of oil everywhere, I don't know how they got there.

_{This was the second time I drew Knux, please don't knock on me}

Edit: Forgot to colour Amy's bracelet's.
