rooftop dancer wip

I've lost all motivation to finish this, so I'll post as is, and maybe one day I'll be inspired will pick it up again and colour it. I think it's a combination of my own exhaustion and frustration in the mistakes that I've made that had killed my will. But maybe in the many peaks of my valleys I'll have the drive to salvage this from the ginormous unfinished pile that is my artistic non existant career.
perfectionism is bad, but I can't help it, and I've made so many stupid mistakes on this it just makes me mad (both angry and crazy). So many lines crossed, so many scores in the paper, and the damn sketchbook doesn't have 90 degree corners; so when I made great efforts to make the background stable looking and "realistic" in terms of perspective, at least, my efforts were thwarted and I didn't figure out why until 3/4 ways in - so then I got sloppy.
And I thought this had potential, I was so exited when I started >>;;
maybe I should crop the left side?
