I'm enjoying your AVN!
I like the MC's looks and understand that he is an 18-year-old guy with a bit of a baby face - which is fine by me.
I know guys like him in RL - they get carded in their late 20's and they will look younger than their years for most/all of their life.
Some would call it a blessing of genetics, others - androgenous/butch lesbian/etc.
Different people project their experiences/likes/dislikes onto characters in all forms of entertainment.
In a visual novel, it is easy for people to find common ground/fault with a character's looks because there is no need to 'fill in the blanks' the way we do when reading a book.
The story and part of the way Gianna relates to the MC relies on the way you created and portray the MC - an increasingly confident, brash, boyish looking guy finding his way and taking some risks with the ladies - regardless of the roof they live under...
I'm looking forward to more Mike/Gianna time as well as seeing how the other women react to Mike.
There is no need to recreate your story/change the look of the MC etc.
It is your story and your creativity bringing it to life.
Those who enjoy it will stay through time and those who do not will leave.
F95 is a forum where a creator will never get the kind of genuine engagement they will from their $ supporters on SS, for example.
'Anonymous' user ids - some primary ids and some alternates for the sole purpose of dissing a creator - will never give you the consistent engagement that your $ supporters will.
IMO - better to spend time creating your AVN and engaging on SS than here on F95 in any kind of flame war where you lose and waste your time because you are trying to have genuine engagement with people who, at best, simply don't like some of your creative choices (nothing you can reasonably fix) and, at worst - are simply trolling you under the guise of offering 'helpful' commentary.
Let your story and your delivery of that story speak for you and the rest will sort itself out.
Cheers!!
