Lines

in the superimpossed lines exercide , there a many good lines but I see some that are wobby and some lines are arching. The arching is on the second page, I could be wrong I see your sketchbook is bent that could explain it. If they are indeed arching try counter arching them while drawing with your shoulder

Ghosted lines

The lines look overall look nice and confidenty drawn, some lines have a wobble and I see one or two that arch but most look good and plotted, ghosted and planned.

Ghosted Planes

I see some archig lines that are not straight, for example first page bottom right planes. The lines seem to be bending. For ghosted planes use the same method as the ghosted lines, dont over think it. Use the same method you use for the ghosted lines for each line of the plane. With practive this will get better.

Ellipses

Your ellipses look confident, planned, ghosted and executed with confidence. The table of ellipses exercise has some ellipses that are not touching the walls of the tables or other ellipses. However in the second table there is visible improvement.

Funnels

In the funnels exercise most of your ellipses are in line and cut by the minor axis. However in most of your funnels I see that the ellipses do not increase in size as the go outward from the center to make contact with the funnel arcs. They must be more like this.

The bottom left funnel has ellipses that are not in line with the minor axis they are slanted. The look like this.

Some of your ellipses are also at different angles.

Boxes

Plotted Boxes

The plotted boxes look distorted. Many of the lines are not straight. Your initial lines should be straight and perpendicular to the horizon.

Your vertical lines should be perpendicular to the horizon.

You shoudl follow the steps to a tee. A straight line perpendicular to the horizon.

Establish the widht and depth

Draw the back vertical edges

Best is for you to re-read the instructions on the plotted perspective again.

Rough Perspective

The rough perspective captures the essence of the lesson and remember for rough perspective the vertival lines of the box are perpendicular to the horizon, and the horizontal lines are paralell to the horizon.

Rotated boxes

The boxes are not rotating well, rememebr you can use the boxes you have already drawn to figure out the orientation of teh boxes you will draw. Your lower boxes look like this

https://d15v304a6xpq4b.cloudfront.net/lesson_images/ecf802d0.jpg

Many are not drawn through , look at the lesson again and remember to plot your lines. A positive is that you are not drawing over lines.

The rotated boxes left side center is not rotating well. The top lines convert to the same point similar to this ->

Organic Perspective

It looks like You exagerated the first three lines that we draw for the boxes, try and keep them simple(remember to plot these lines too)

https://d15v304a6xpq4b.cloudfront.net/lesson_images/ecf802d0.jpg

Try to not distort it too much now

https://d15v304a6xpq4b.cloudfront.net/lesson_images/40c53985.jpg

and maybe copy the example a few times to get the feel of it

https://d15v304a6xpq4b.cloudfront.net/lesson_images/b6b205ea.jpg

I will say redo the ghosted lines, rotated boxes and Funnels and keep everything above in mind

linework:

Your lines are long and confident however something notice throughout your linework in general is are some bends and curves around the second half/ ends of the lines. IT seems like you are making marks and then halfway through drawing you realize you are going to miss your mark and make a correction. When lines we should prioritize confidence and straightness over accuracy. When drawing lines ghost the motion repeatedly and when tou feel ready to make the mark for real focus on the sensation you have been building up. Addtionally when making liness don't be afraid to place points multiple if necessary to give you a better sense of direction and aiming.

Planes the issue with your planes mainly stems from your linework. You also have some issues with finding the center point the non corner lines are very off line. When drawing the center lines their is no magic trick but you must make sure they pass throgh the point of intersection between the ellipses. I think what should do is place points on the sides of the planes that have the center point between them.This issue also affects your ellipses. The center of your ellipses should be be at the point of intersection between the corner lines. And the the minor and and major axis of the ellipse are basically the the T formed from the center lines all you have to do is connect them.

Ellipses:

Your ellipses in general are ok you are drawing them multiple times. the only issue I would say is moter control which only comes with more practice and ghosting.

However the tunnel ellipses have a couple problems. First when seem to be having problems with your center line so just to understand you can make the tunnel first and then add the line inbetween. Also rembember what I said eariler about using points to help guide you. I think the crux of the problem is that you are attempting to place to many ellipese in between them The point of the intersection is for them to gradually shrink and then grow back to their original size at the end of the tunnel. addtionally You have a tendency to tilt your ellipses when doing this your eplipses minor axis should be parrallel to the center line you drew. Ideally it should be the minor axis which is it's point.

Boxes and perspective.

Your boxes and persepctive in general really need some work. Do note Im not trying to be harsh or mean, but your are fundementally constructing those boxes incorrectly. You should reveiw the concept of a vanishing point. You seem to have intreprested that points making the corners of the box should converge with the vanishing points. You are wrong. The lines between the corners(the edges) converge towards the vanishing point. This is espeacially true with your plotted perspective(the one where you used the ruler. Some of the sides of the boxes are also wrong. When making box you are technially making a collection of planes. And some of your planes are squares they are triangles like bottom of the center box in your organic perspective in the bottom attempt is the best example of this. Thier is a specific technique you will learn later on in the 250 box challenge called the Y method.

All in all this was a decent attempt good job move on to the 250 box challenge
