Edit: oops didn't see the post above!
I did some minor corrections and added the first colour.
Though I have to say I really don't like this pose. At all. It looks awkward and unnatural. I vote we go back to the old one:
Spoiler:
Not really an edit, just noticed that PeckanPie coloured a part that is not part of the body, so I turned that white again.
The colours are great, but it's extremely pillowshaded. I think everything has to been redone. But it's a great way to practice, so it doesn't really matter. If you were to give it another try, try to look at existing sprites. I would recommend looking at Raikou for this one, if you want to try again :)
