The VG Resource

In Advance Style obviously. =P Edited off of Tails. I'm Working on doing alot of Poses of her. All the sprites curently on there are complete so you can use them already. Just give credit. Tell me if you think they are good.
Oh, Here's Her Official Art so you can compare.

edit = bad in some places. But this one seems good

The tail seems a bit too thick
You should add the eye markings
you should shade the head a little.

I would strongly recommend not to do edits.

If you really want to, you should use Cream as a base, since Marine is around the same age.

The face still looks like Tails. Not a bad start.

Mix edits of Tails and Cream, then, Fireshock?

Well, it's an okay start... But the only sprite sheet of Marine that exists (try to prove me wrong. Just try.) shouldn't be a (somewhat) mediocre edit of another. Custom? But keep it in Advance style, of course.
