Animation comissions info -  Animation scenes comissions - OPEN!Ok, so I decided to open animated type of comissions again. This time it's animated scenes - like a fake screenshot but moving^^ And maybe I just kicking myself again with prices cheaper then they shoud be, don't know... But I need to start with something, so here - 
What it would be? Like I said before - animation with background and effects if needed, like a part of anime with your characters. No transformations, though - this time I want something easier^^
Examples - (fullview them, please^^ Some previews are shorter then actual animation. And it just look better with fullview, right?)


What I would draw:
1) Girls. I'm better at drawing girls^^
2) Few characters at one frame are ok too, but only two if they're moving. And as much characters as you want if they act like a part of background
3)Simple movements - hair waving by t
