While I'm not an active member, and this is just my own opinion (and being a little biased), I do agree.
I think the current green skin, while being here quite a while, is a bit much on the eyes, at least for me, and is pretty old by this point. The new Vaati skin is an improvement, because it's darker (like my soul), but it still seems kind of off to me, like the colors don't mix well. Again this is just my opinion, if others agree or disagree that's fine.
When I made these ones a while back, I was pretty proud of them, and thought they were nice. Unfortunately no previews up anywhere for you guys to see, since the nuZFGC stuff was taken down off GD-U a while ago, but if you want you could throw one up (perhaps the Deku theme, my personal favorite) and see how it fares, if it's fully compatible and such, maybe put the other three up as a test, see how people like them.
