Please add more control over the body, such as leg size, thighs, muscles...etc.
We already have that in progress (which you can test by using the nightly builds). Stay tuned for the next update!
That's great, I'm planning to buy it. I have another suggestion, which is to make the character's perspective from the right and left side and from the back, as well as making some poses in which the character is sitting, sleeping, kissing...etc
Noted. Will add those things gradually in the future.
