/bbwdraw/ - BBW Drawn

Get help on your WIP roadblocks here. Couldn't find any relevant existing thread for this topic, and didn't want to dilute the draw request thread. I can't seem to get my art past the inking/rendering stage because the structure begins to fall apart. I spend about 30 minutes to an hour on the rough sketch, then get stuck in a loop where I'm endlessly redoing the shading and linework until it becomes a blurry mess. Any tips for Krita/CSP/Photoshop users?
