Top notch quality animations,but i can't understand the passion with the extravaganza body proportions.I make a quick edit and the models still looking amazing even without the oversized parts. In Mother's Warmth 2, lips in some scenes (hospital) looking kinda like ..Orc?
my visual tastes do align more with your idea of less oversized body parts to represent attractiveness or hypersexuality. I came to find Jackerman here due to the interspecies content. But now I found I've stayed for the voice actresses.
about those lips, I think its just something that he may not have figured out yet. Animation is going to stretch and bend moving parts so keeping to even any one poster-perfect representation is already going to be tough. In the end its what the creator has deemed as enough to let out into the world. If we don't like it on the whole or parts of it aren't satisfying enough to keep seeing what he creates, while we withhold judgement, we could always move on to the next beautiful thing we discover out here/there.
