Hey, Flamingorosso.

Good job on finishing this lesson. I took a look at your work and here's what I've notices:

Lines

Starting with your superimposed lines. These are very wobbly. Although you did a good job in keeping them tightly packed together, you clearly drew them too slow in order to achieve that, sacrificing the smoothness of the lines. What you want to be focusing now is drawing the lines with confidence and with the motion coming from the shoulder. Your can check this comics strip that illustrates what I mean.

Your ghosted lines are much better. There is some arching in a few of them, but overall they are good.

The ghosted planes exercise is also nice. Again, some arching is noticeable, specially on longer lines.

Ellipses

Your table of ellipses are overall good, although there still wobbling in a lot of them, specially on the rounder ones. Don't forget you should be ghosting your lines and then draw them with confidence. Don't try to slowly trying to draw the perfect line or ellipse, while trying to course correct them during the process. That will result in wobbling most of the time.

Your ellipses in planes look better, but still suffer from the same problem as before.

The funnels are mostly good, as you did a good job maintaining most of the ellipses aligned with the minor axis.

Boxes

You did a good job in the rough perspective exercise keeping the horizontal lines parallel to the horizon and the vertical lines perpendicular to it. Most of the perspective lines are also converging, which is a good thing. In some cases you tried to correct some wrong lines by drawing over them. Avoid doing that. It's easier to spot and understand your mistakes when there's only one line.

You also did a good job on the rotated boxes, although some of the lines are very messy as a result of drawing over them.

On your first page of the organic perspective exercise your flow of the farther away (smaller) to the closer (larger) boxes is not quite correct, as you have large boxes in the middle of the line and then you have smaller boxes again. You should go from small to large, in order to create the perception that the large boxes are just closer to the viewer than the smaller ones. Also, when you overlap the boxes you should still fully draw the one in the back, as if the boxes were transparent and you could only see the lines. Your line work here is better, but you are also going over the same lines, which is something you should definitely avoid. There are also some boxes with dramatic foreshortening, which gives the impression they don't belong in the same 3D space as the others.

Overall I think you did a good job in this lesson. There are definitely some aspects you need to improve, specially the wobbliness of your lines. Always draw them fast with motion coming from the shoulder.

In order to improve, you should keep doing some of this exercises as warmup before drawing.

Congrats on finishing lesson 1!

Your superimposed lines have quite a few wobbles. Remember, confidence always matters more than accuracy. It's alright if your lines don't perfectly overlap, as long as they are straight. There are also a few instances where there is fraying on both ends of your lines, which might mean you aren't taking the time to place your pen where the line begins before shooting for the other end. Your lines should be confident, but they should be planned as well. The same things apply to your ghosted lines and planes, though they are generally pretty smooth.

Your ellipses have quite a few wobbles. Remember, confidence always matters more than accuracy, so your ellipse will be a good one as long as it's smooth. Your ellipses in planes also tend to sacrifice that round, elliptical shape in order to force them to touch every side of the plane. Another minor thing I noticed in all your ellipse exercises is that you tend to draw your ellipses with more than three passes.

Your perspective exercises are generally well done. While your convergences in rough perspective and organic perspective are sometimes off, you will have a lot of opportunities to practice those in your warm ups and the 250 box challenge.
