No Mutants Allowed

That is where I have been stuck for years.

That is the real pain in the ass: to have skill in drawing.

You can also find an artist to do it for you, altho that requires money. Alternatively just write it as a straight up novel.

Certain stories work better in visual form.

Further alternative. Just start drawing. Yeah we all suck at the beginning, some of us suck even years into practicing, but that's the only way. You could also try pitching it at a editorial and they can find an artist for you.
