Hey Nick!
Just a general recommendation for any kind of draftsmanship. To indicate changes in volumes, soft folds, and minor details, you should stay away from using lines. Lines work best when indicating contours of forms, but changes in planes, folds, and small details benefit better from color, value, and general painting with light.
Less is more! Keep only the lines that have a strong, clear purpose. If you get rid of all these "orphan lines" on your painting you'll notice it will look more attractive and your brain will still do a nice job of deducing form.
