Superimposed Lines: Overall Good. They are nice and confident and free of any arching. Just remember to take care when setting down your pen. There should only ever be fraying on one end of your lines.

Ghosted Lines: Again, good. One stroke one line as instructed. I'm not worried about some of your lines missing their marks, that will improve with practice. However, I am noticing a slight arch so some of these lines. Remember to take your time and always rotate the page to the optimal angel to get that clean straight stroke from your shoulder.

Ghosted Planes/ Ellipses in Planes: Kind of a mix bag on this one. I'm not sure if it's the quality of the photo, the crippled paper or a lack of confidence but there is some major janky action to the lines on the first page. Thankfully the second page is much smoother. Again we have some lines with a slight curve to them. Just keep rotating that page!

Table of Ellipses: Very impressive. There all drawn through twice and oh so smooth. There are a small handful that overlap a tad too much but that is a nitpick for a very well done assignment.

Funnels: Again very good. Majority of the ellipses are touching with minimal overlap and the minor axis is spliting most of them into equal halves. I do believe the minor axis is misaligned in the bottom right hand corner. But again nitpick.

Plotted Perspective: Perfect. It's everybody's favorite exercise.

Rough Perspective: Overall Good. We got some wobble to the lines but the boxes are drawn through and you have your guide lines head back to the VP. Don't think about too many things at once. Plot a set of lines and focus on that stroke. Keep in mind that every single Horizontal line should be parallel to the horizon line and every single vertical line will be perpendicular to the horizon line. There should be no lean or tilt to those lines.

Rotated Boxes: Considering the degree of difficulty, this is not too bad at all. Although the perspective gets a little funky and your missing some boxes on the top and bottom, the lines are stroked with confidence, with minimal wobble. Also I always appreciate hatching. It makes the exercise soo much easier to see and critique.

Organic Perspective: The essence of the exercise is there. The boxes are following the curve and change in size as the fall towards or away from us. Remember the one line, one stroke rule. You should only go over lines to add weight, not to correct them. All in all we're going to learn more about the "Y"method of constructing boxes and 3 point perspective in the 250 box challenge.

Overall Thoughts: Very good. The exercises are complete and you seem to understand the gist of things. Just be sure to re-visit these exercises in a regular 10 - 20 minute warmup before each drawing session to help improve line quality and accuracy. With that said I feel you are ready to enter the 250 box challenge. Cheers and Happy Drawing.
