Hi, SalveteVictoria!
I'm really happy to hear I inspire you to make your own visual novel! >\\\< I believe that anyone can do ot given the time & effort.
And yes! Feel free to ask me anything ^.^- I suggest to try and experiment with Renpy first though. It's a lot more convenient & efficient since I can't be there to show you directly.
At first, try simple things like; changing title screen's background, how to insert your own sprites in game, and customize the textbox/GUI!
Ren'py is really famous in lemmasoft forum so you can find lots of tutorials there! You can google 'lemmasoft how to customize GUI' and it will pop out x'D I spend a lot of time here trying things through errors & trials.
It's also OK if you want to ask me about what art assets needed to make a VN ^_^)b
Come again!
xoxo,
SweetChiel
