Hi Profundum Team, the models I have previously given detailed feedback on the possibility of moving to a softer / sweeter tone so won't repeat there.
Thanks for sharing the sample animation, so here's some quick observations I hope will be helpful:
1) MC's dick has a lighter color tone compared to the rest of his body esp. the legs, you might need to make some adjustments to harmonize.
2) In terms of camera movements, the general rule of thumb is to identify the focus areas and then hold them for at least 3 - 5 seconds before moving to the next focus area. The current presentation where the camera keeps moving without stopping is probably not ideal as it does not draw attention to anywhere in particular.
3) Taking reference from porn practices, the focus areas for a reverse cowgirl are usually i) a front shot that captures the entire female face-boobs-pussy action moving up and down (more common is to have the camera slightly below cock level inclining upwards slightly), ii) close up of genitals, iii) top down showing female face with bouncing boobs and iv) male POV of butt bouncing against stomach.
4) You don't need to do all 4 focus areas in one animation ( I think 2 or at most 3 will suffice), so an e.g. sequence would be start off with (i) hold for few seconds, close in on (ii) hold for few seconds and the move upwards and do (iii) for a few seconds before looping back to (i)
This is for one smooth animation with multiple focus areas. Alternative is to break down each angle into different animations and cycle them automatically or allow players to choose.
Alternatively you can go for a more innovative and "fap friendly" way like The Inn which players can change anytime but the story and dialogue will still continue.
5) One last thing is the lighting, although the shadow against the wall is indicating a single source of lighting angle at around 1 'clock from the characters, there are no shades on the characters themselves which makes the whole experience a little unrealistic.
Hope this helps.
