I love your picture! It's so beautiful and eerie at the same time.
I don't really like using my eraser, because I hate the little bits that come off of it after you erase something. And so, my sketches are very messy and have a lot of little notes to remind me of what the picture actually is.


But this also means I have less concrete reference to go off of, so I end up spending too much time on one part of the picture. Currently, I'm trying to just use the eraser.
