Your superimposed lines are good work. Some groups have very little fraying and all in all confident linework.

Your ghosted lines are confident and most of them are straight. Few longer lines show a bit of arching.

Your ghosted planes look good. Some lines show a bit of arching here as well. It might help to draw more from your shoulder. You could incorporate this exercise into your warmups to see if it improves.

The pages with your ellipses in tables are full and you have drawn through your ellipses. You clearly aim to fit them against the marked borders. There is a little bit of overshooting visible. Good job on this exercise.

Most of your ellipses in the ghosted planes look good although some seem not to be very evenly shaped. Try to aim for a smooth and evenly shaped ellipse.

Your funnels look very good. The ellipses are confidently executed and drawn through. Most of them line up with the marked borders and they line up with the minor axis.

The first two frames of your plotted perspective looks very good. You used a ruler and your horizontal edges seem to be correctly plotted. In the third frame however some of your verticals seem not be perpendicular to the horizon line. One way to avoid this is to take more time to align with the ruler.

You used the ghosting method for your rough perspective which is good. You correctly used one vanishing point in the center of the horizon line. The front and back faces of the boxes are rectangular and you used the line extensions correctly with a pen of another color.

Your rotated boxes are actually rotating which is good. You have drawn through your boxes and all the steps of the exercise have been completed. The gaps seem to grow a bit the further away from the center the boxes are. Try to keep them tight.

You have used the ghosting method while drawing your organic perspective boxes. Some of the lines seem to wobble a bit. Try to keep your linework confident and smooth. It might help to repeat the steps of the ghosting method more often. The foreshortening in your boxes is not dramatic. Good work.

I mark this lesson as complete.
