Okay, I'm at a loss here. I've been working on this WIP for a good while:

(Futa/Loli Warning)

I finished sketching it out and I want to clean it up with loose shading/coloring, but I have no idea how to go about doing that. I legit only know how to do clean color for clean lineart. I started attempting something with the hair, but I'm not digging it too much. And though I would kinda like to keep going with what I was doing, I don't feel the result would be worth the time I'd put in (just the one twintail took me ~35 minutes). What I want is to kinda make the pic look nice, but I don't want to invest the time it would take to fully polish it. I want the lines to be cleaner and to have at least some shading or coloring, but I feel like everything I try to do ends up taking just as much as it would to do clean ink and color. What am I doing wrong? What should I do? I'm completely fucking frustrated and have no idea how to move forward with this pic.
