@Watercolour that digital render in greyscale looks absolutely amazing. Really good
As per feedback:
I guess try to work on more confident lines in your gestures. Ghost in a line before you draw it and try to work on pushing less hard on the paper. Practice holding your pencil in different ways (check google on different grips or observe how artists you admire hold their pencil while drawing) and see what benefit each grip has.
Keep it up! Can't wait to see you progress. You're doing great =)
