I can help out with such a project. I first got into doom level editing over 20 years ago and since then I've gained experience in creating graphics, sounds, and such as well as modding for gzdoom including decorate and zscript code experience. I can PM you some of my work.
Looks nice! It's cool that other people do video game editing here. I'm into modding for gzdoom but can't make a game from scratch, that's impressive.
