I think, and I am relatively new to this, that you need to review how straight and accurate your basic straight line drawing is. Throughout the images it seemed like most straight lines were actually shaky, curved or overshot the target.

I think the strongest exercise you did was the funnels.

I wouldn't pass this. I think you need to spend time daily just working on point to point straight lines to get more control over the pen. This aspect is a core skill, and you will struggle with the next stages without it.
