It is so nice to read such an intricate review! I am happy you had fung with the game. I am going to add two more poses, with view from the back, and I'll try to think abut modular system wuth various faces at least, maybe arms (but that won't work well with costumes like latex suits that have gloves). Also I noted the idea of changing camera orientation and maybe will change static camera positions to manual panning as you suggest.
And yeah, I do have ideas for much, much more BDSM stuff! I already prepared some shibari for the next update, as well as a special photos with rope bondage on chair, and many more to come, I hope. This is a theme I am personally very interested in ;)
