1. Lines look excellent to me, very straight, very precise.

2. Ellipses have a great flow and smoothness, though I think we are advised to loop two max three times, I suspect you may going round a few more times which can make it hard to see where the real shape is.

3. Perspective. Plotted Perspective is fine. With the Rough Perspective, I think the side facing the viewer should not be slanted, in effect a 2D rectangle with to sets of equal, parallel line. In some instances the sides facing the viewer converge which doesn't work with One Point Perspective and I think undermines the rest of the drawing. Not a big deal, we'll all be drawing so many more boxes before this is over. The Rotate Boxes looks great, though I think I see in the construction some extra lines which feels more like how one draws when sketching in pencil but I think on Drawabox we are only meant to draw the lines we plan to use. The Organic Perspective looks great with a nice flow and good sense of depth.

I personally you shouldn't have any problem moving on to the next stage, which I think is the 250 Box Challenge.

I've noticed that you have moved on to the other lessons but this Submission is still in the December queue, which I'm doing my damndest to clear out so... here you go.

Superimposed Lines: Good. The lines are smooth and confident and free of any wobble. Their are a few instances of fraying on both ends of your lines. Be sure to carefully place your pen down on its mark before making your stroke.

Ghosted Lines: Good. Again nice and confident lines. I'm not too concerned about you over and undershooting your lines at this state. We'll improve that with practice. I would advice your to implement some smaller lines next time around as well. We want to get that shoulder accustomed to drawing any size of line.

Ghosted Planes: Good. Nice two full pages with a variety of angles. Remember one line, one stroke. We should not correct any of our lines no matter how bad we missed. Also make sure to plot all of your points; the cross bisecting your planes included.

Table of Ellipses: Solid. Two full pages and your ellipses have that smoothness that we are looking for. Make sure that you only draw through them no more than 3 times preferably twice. Also be conscious that none of your Ellipses are tilting to the left. Be sure to practice some of the next time you revisit this exercise.

Funnels: Good. The Ellipses are nicely fitted in the plane with the ellipses being nice and smooth. Take special care when setting up your funnel. If the minor axis is misaligned it's hard to get the exercise to work. Notice that some of your ellipses have a slight tilt to them that would have thrown them off the axis as well. Overall it's still a good effort just keep in mind these minor but important details for next time.

Plotted Perspective: Solid. Much of the exercise is correct. But we do have a couple boxes missing lines and some of the hatching is a bit messy. If you're not using one, I would strongly suggest getting hold of a clear ruler so you easily keep track of your lines.

Rough Perspective: Very Good. The boxes are all drawn through with guilde lines drawn with a straight edge and heading back towards the V.P. Many of your horizontal and vertical lines are close to being Parallel and Perpendicular to the horizon line. Notice that the slight tilt to those lines makes the boxes less sturdy and throwing off the perspective. Also keep in mind when adding line weight we only add one additional stroke to the silhouette of the box and never use it to correct lines. Again hatching is a bit messy. Be sure to carefully plan and ghost every stroke. Yes, even the hatching.

Rotated Perspective: Good. The image is nice and large, and the hatching work is actually quite nice. I'm seeing some rouge lines here, though. Be sure that your carefully plotting your points and committing to them. We are not expecting instant success with many of these exercises. Also be aware that your missing 2 boxes. 2 on the top, and 2 on the bottom. Lastly many of the boxes are not quite rotating. Be sure to read the common mistakes part of the lesson plan when you give the exercise another go. (https://drawabox.com/lesson/1/rotatedboxes)

Organic Perspective: Good. The exercise is designed to get you to think of 3d space, not necessarily succeeding at it. We'll learn more about the "Y" method of creating boxes and working with 3 point perspective in the 250 box challenge. The exercise itself is a good effort. We go the boxes following the curve with a good variety of sizes and angles. I'm having a tough time seeing your plotted points. If your using them, then good! If not... Bad! No matter how complicated things may get always go back to the basics of: Plotting your points, Rotating your page, Ghosting Your Strokes, and then, with a nice smooth stroke from your shoulder put down your line.

Overall Thoughts: Very Good. The exercises have been complete and you followed the instructions. Your line quality is solid and your ellipses are smooth. Continue to revisit these exercises as your work your way through the 250 box challenge.
