Good start. You have all the prime building blocks for a great NTR game. Good models, a solid plot start, cute innocent characters, an antagonist.
I also think it is wise to have most of the backgrounds be 2d maps, as that lessons the posing work.
A bit early to ask for pay, but I'll be looking forward to seeing how this goes, and it I like what I say, will hop on board the subtrain.
Good luck!
