Still in the planning phase BUT after a "why haven't you..." conversation with a friend I've started to work on a YCH featuring my characters~

Rough idea is I'd be a 1-2 page comic featuring the OC of the buyers choosing. Something SFW and with all the wholesome interaction vibes I'm about <3

Do have an artist on board, but still working out logistics.

What I'm thinking is OC's baby shower and the buyers character having some 1v1 interaction time with them.
Buyer would choose:
- Any OC of mine (including AU Nina in a modern setting, not her canon tribal)
- OC's outfit, though realistic (ie not sling bikini or French maid outfit ;p )
- The usual minor tweaks like expressions, reactions, text/conversation, etc etc

Now my questions for ya'll...
1) Should it only feature the two characters? Or should there be a single whole room establishing shot with a bunch of (cheap) OC cameos and then the rest be 1v1?
2) What sort of actions/interactives appeal to you? (Conversation, belly reveal (shirt lift), having hand guided around, feeling movement, listening (stethoscope or doppler?), etc etc).
3) What sort of conversation would you want? Is there something you'd like to hear her say? Any questions you'd want to ask?
