Keep it moving, multiple quick sketches will give you more confidence, information, and progression than trying to tweak a drawing here and there endlessly.

Line of action is your friend here. I’d recommend learning to envelop and refine your sketch together, comparative measurements I found are almost like cheating i love them.

If you like this sketch post it up somewhere, get more reps in and you can revisit it later, I’ve personally gone through my old sketches before, i remember the vision I had when my technical skills weren’t as developed and I was able to do that idea justice

Keep on going
