Wow, great so far!
I just take some notes on her outlines (being a bit nitch picky), as I noticed some color bleeding in the left character. Also, the pussy mons of the left character is....too simple (that is, perhaps a bit more detail, a small clitoris, some meat). The current pussy outline is also not comformed (like being drawn on pencil without smooth curves). For example, I would do something like that:
At least for me, when seeing a pussy like that, it gives more 'shy' reactions, as 'hey, please cover that yummy pussy. That's embarrassing'.
Also, for Era herself, perhaps some of her pussy meat can appear in the sides of her sling bikini. Something like that (I also removed some of her 'thigh outline', because I imagine that too much line there kind of remove her yummy body style or something.
See? There is 'something naughty' there! When we play, we notice things like that. We imagine 'when' we can see her naked in order to see that naughty pussy exposed. We get different desires. During walking, or if an encounter talks to her, we imagine: 'wow, perhaps that sling might be pushing her pussy too much', or 'Wow, I imagine when that pussy gets wet', etc.
Trust me, players that move and look at those characters get enticed just by noticing they are revealing more 'meat'. I remember playing some games where, even a static CG could let the player focused and aroused in different situations just because the 'good bits' are there. We dont need to be so detailed (all labias, divisions, etc), just the 'some meaty genitalia' focus. You can close her pussy more, but something (like an erect clitoris) will entice the player.
For example, this picture of the same game (a bit more detailed and exposed pussy).
If you want, I have a 'huge' PNG of pussies I use when decensoring. I then apply some scaling, smoothing, 'pushing', and color changes.
