While these are an improvement you're still noticeably redrawing as well as adding additional lines and line weight to marks you shouldn't be.

As explained in the box challenge instructions here if you add line weight to your form intersections it should only be to overlapping lines to help provide clarity to the image. You're adding it seemingly randomly while also redrawing lines which makes your work messier and harder to follow than it needs to be.

In the organic intersections exercise you're not always drawing through your small ellipses on the end of your forms, and you're redrawing your contours as times as well as not drawing them as confidently as you could be. I'm also uncertain why you've gone over some of them with a brush pen, none of these should have line weight applied nor would it be applied with a brush pen.

I'll unfortunately be asking for another page of each exercise, I really can't move you on until you're following the principles of markmaking correctly as the later course material will be much more difficult if it's difficult to follow what your lines are representing.

To reiterate the principles of markmaking are that you should first take the time to ghost and plan your line, and then draw it in a single smooth confident motion. Don't redraw over mistakes, work with them and plan accordingly to prevent them the best you can. If you apply line weight do so consistently with clear rules (in the form intersections exercise only applying it to the overlapping lines).

I'm aware you can do this as you've done it before in the box challenge. If you aren't certain of the instructions then please read through them again and go back to prior lesson material if you need further clarification on these ideas. This is ultimately an issue caused by choice not by your ability so I don't want to discourage you into thinking that you're incapable of doing this. The fact that it's a choice is also why we need to be as critical of it as we are.

If you have any questions before getting started feel free to ask them, otherwise I look forward to seeing your work once it's completed.
