Some ideas for the scenes. I would be glad to see something like this from you in the future.
1. Considering your Amelie's body, she would look perfect in a scene like this.
2. Yoga is also good, but such cycling is a combination of pleasant with useful.
3. Just as a variant of one of the successful poses.
Woah!! This is super detailed and cool! I like the 1st idea alot, and also like the idea of yoga as well! I think I'll take a stab at them soon!
I'll use a male character this time, I've learned my lesson here! 
A few suggestions.
Don't use horse cocks.
Your Amelie model is just awesome, so let the scenes with her be awesome as well and realistic sized.
The cock I used is actually very similar in size and shape to MC from game. But I'll try to find a good middle ground for realism.
Your Amelie's breasts and ass are beautiful, but when you create a touch to them in your art, they become like a deflated ball for European football. Do you have the opportunity to fix it? Make them more solid?
Because there is a feeling that Amelie is now deflates like some kind of rubber doll.
This is basically due to me still learning weight painting. However unless they have breast/butt implants, there is obviously a rather "ball-like" give for many breasts/butts on the anatomy spectrum. Again... just something I'm trying to find a middle ground of, as I prefer to simulate realistic bodies and not rubber dolls. Main game also has examples of this squeeze effect.
Also be careful with facial expressions. Sometimes art looks much better without them at all than with them)
Yaaaa... I'll admit 2nd expression isn't my best, again... working on it!
An important detail in such scenes is the rotation of the female character's head, which should not exceed 45 degrees.
Otherwise it will looks not good. Like some broken neck.
Don't think either render broke this rule. But if you've ever backed a car up before or turned around, you'll know a human can rotate their neck and torso in conjunction to look behind them...
Good luck. Be sure to share your masterpieces with us)
As long as everyone is cool with me sharing them, I'll keep making/sharing them as I practice!! Fanart is a great way to learn, and there is sadly no forum for it for this game.
