How many chapters/how many more updates are you planning for this VN to have?
The reason I ask is since you're clearly already working on a new game, which is somewhat understandable if this is only intended to be a short story (maybe 5 or 6 chapters), but seems strange if this is intended to be longer.
If it is intended to be longer, then it would make more sense (in my opinion at least) to focus on a single project and build up a fan base; based off of reliability and quality of work.
This is, however, all based on the assumption that you aren't doing this full time and thus your available time to work on even a single project is already rather limited.
Then again, even if you were doing this full time, I'd still think it wiser to concentrate on a single project until you either built a decent fan base (income from it) or were nearing the end of the current project.
Anyway, these are just my opinions, so feel free to take them however you like or ignore them entirely if you wish.
Now onto the VN itself I guess.
The premise itself has some decent potential to become a big in depth story/game, however currently it feels very light in content and like the story isn't particularly a priority.
It feels as if the story is somewhat of an afterthought to the images and is written halfheartedly just to lead from one image to the next, however I guess that could be due to where your experience lies.
