I would honestly really LOVE to see the finished result for this, it looks like it'll look amazing. But of course since it's really just a doodle it's obviously gonna be really messy and stuff. But I don't see much art with this kind of look to it, or really anything that looks similar to this. But I think it's really interesting and just like it'd be really pretty. Just needs some cleaning up and maybe shading/color. If you ever did finish this I'd be over the moon because I think it has real potential.
But as usual even you're doodles look really cool. Can't wait to see more!
