Since you asked for honest opinions and advice, I'll give you some: forget about those terrible animations.
I'm sure a good part of developing and rendering time was put in those, but believe me, until you master all the tricks it's not worth it. The sex scenes and positions would have been way hotter and more beautiful if you had just resorted to still renders. Many still renders showing the characters reactions, different angles, etc. Those animations were robotic, and the assjob animation was downright weird.
You are a fantastic creator of renders. They looked amazing! Make use of that until you get the technique and hardware needed to make decent animations.
BTW, the milf's ass looked so fucking tasty
