Feedback for Lesson 1 homework.

Lines:

You've made a great start! DaB prioritizes drawing confidently over accurately, so continue to develop that first -- ghosting as much as you need, placing the pen on the starting dot carefully, then making a line quickly between the points, even if it's not accurate. I notice some of the Ghosted Lines/Planes have lines that are overshooting both the start and end dots. I encourage you to place the pen carefully on the starting dot; it's OK if it over/undershoots the starting dot.

Ellipses:

They look great - more confident than the lines IMHO. A few of the Funnels - especially the corner-type ones - aren't exactly aligned with the minor axis lines, but not a big problem. Continue drawing tables of ellipses or funnels as warmup/practice, as you keep doing more DaB (especially when doing the 250 Boxes). I also recommend drawing over the ellipses twice only, instead of 3 times as it seems you've done. Without the 'safety net' of drawing over many times, you're compelled to develop more confidence while you focus on accuracy/keeping them inside the boundaries. I had the same issue, and drawing over twice helped a lot with my ellipses.

Boxes:

Rough Perspective is where the rubber hits the road for most people! The linework is starting to wobble a bit in Rough Perspective, but that's quite normal at this stage, and it becomes confident again in your later exercises. A box is a collection of straight lines, so if you can make confident ghosted lines, you can draw a confident box.

IMHO, Rotated Boxes is the most challenging exercise in Lesson 1. While some of the boxes further out from the centre don't rotate enough (ie. the whole lot of boxes has a more squarish shape than a spherical ball shape), still, well done with doing and finishing it! (If you were still unsure about rotation, here's the exercise's page.)

And good work with Organic Perspective. I notice that you've "done over" some lines repeatedly, presumably to correct mistakes. I encourage you to not get into the practice of doing-over mistakes: let them stand as they are. Not getting a chance to do-over mistakes means you're compelled to learn to ghost/draw your next line more accurately, or work within the constraint of the mistake -- both of which are good mindsets to develop for both DaB and your actual/fun art.

Congrats on finishing Lesson 1! Keep using these Lesson 1 exercises as warmup before drawing those boxes -- I recommend Ghosted Planes to warm up and build confidence with straight lines, and the ellipse exercises, as it's good to keep practicing them.
