I promise not to show more of this until I finish, but I'm really pleased with this now. That dark spot in the lower right is just a shadow.
I've completed three repeats on the mock cable, and it has flow now. I'm trying to figure out how I want to do the double twist section in here as a chunk. I think maybe just as I did in the beginning, because I want the focus to be on the cable part, not the break.
