Would you like to come up and see my etchings?

Vicianus is right about lineweight/linequality.It`s clear that your pencils are sharpening up. But I would recommend you to use different pencils (maybe H for the mainsketch and something around 6B for heavier "darker" lines something that doesn’t require you to push down as much).
Arms and wrist are pretty vulnerable;-)
