This version of Cheyenne is not an official version ( cf. CheyenneV2.0_ ) but rather an interesting alternative for certain features, and for this one, it's its clear and precise lineart, flat colors and beautiful gradients.

So if you're looking for a less organic, more cartoony version of Cheyenne, perhaps this version will suit your projects. As this is a tuned version of the original, the addons are fully compatible for even greater flexibility.)
