Hello and good job on completing lesson 1. Here are my observations.

Lines

The start of the lines is good always from the same point but we can see some feathering on the other side which is normal and accuracy here comes with time.

There is slight wobblines in ghosted lines as well. To get rid of it you really have to think and use as much arm as possible and as confident stroke as possible. Again accuracy should come with time.

The same with ghosted planes.

Elipses

Here lies the most notable problem I see where I think you prioritized accuracy. The goal is to have a smooth and confident elipse. To get that you really have to use your arm and do it a bit faster than you probably did to get rid of wobbles.

Same with elipses in planes but less notable.

Funnels are accutrate as well but some wobbles are still present.

Boxes

Ploted perspective looks great and clean. Only thing to have it a bit more presentable and prettier is to apply some lineweight to the silhouettes of the boxes.

Rough perspective looks good, looks like you understand where the lines should go. And again accuracy should come with time so try to minimize the wobbles.

Rotated boxes look nice and clean.

Organic perspective clean.

Boxes wise have to say they look really clean but there are minor errors with rotated boxes and organic perspective like the convergance of the lines which I belive will be solved if you go through the 250 box challenge.

And accuracy and wobblines wise again try your best to draw with the arm accuracy will come later. I only started to notice my accuracy with boxes improve towards the end of the 250 box challenge so do not worry if it doesnt come immediately.

Hopefully I helped you and didn't make to many mistakes myself, and good luck on your future endeavors.
