What was changed?

I actually like the green seeing that it's Halloween themed. Very well use of the regions and different textures.
My only suggestion is that there seem to be white specs on the green texture that look off in some regions.

Thanks everyone for your comments, there are alternative colour variants I experimented with but this was ultimately the best choice.

Guys, if she made this team colored, then it wouldn't even be ghost-themed anymore. That's like the whole point of this color palette.

Eh, the concept is fine as it is, there's no need for it to have team variants

Team colored would be sick. I really just dislike this green though.

Instead of green you could go for a blue-ish color and make a RED variant as well.
