Hi Dopong, like you I just completed the first lesson, so please consider that in my critique.

It seems to me that you didn't use a fineliner in the superimposed lines, I´m not really sure but take an eye if that's the case, other than that you have done a really good job.

In ghosted lines exercises you do a little of wobbling in your lines, I would take more care of that in the warmups when you start the 250 boxs challenge.

Appart of the wobbling, in the ghosted planes and the elipses in planes you do a prety good job, it seems to me that you already have some experience in that.

You did really nice in all the table of elipses, I have nothing to say in that.

In the funnels there are some distortion in the elipses of the extremes, take care of that.

In the plotted exercises I have nothing to say but some trouble in the shadow that you applied on the boxes. All of them should be coming of the same spot. I mean that some boxes have the shadow in the right, when in others of the same frame have the shadow on the other side wich is strange.

In the rough perspective i think you doubt a lot when you do your lines, consider to do more ghosting in the lines, I think that it helps a lot. Another thing is that you don't have to do the same line twice, the idea is to work with the line that you already done to create a strong base.

I have the same problems in the rotated boxes. I think that is important to develop in our minds the sense that you are rotating a 3d object in a 2d space. Keep an eye on the wobbling, remember the ghosting method always and use your shoulder.

I really like the last page of the organic perspective. In the first page i think that you doubted in the scale and proportion of your boxes, becouse in some points you didn't make more big. Try to do the same that you did in the second page, it was a really good job.

One last thing, you did a really nice job, keep it. Do the 250 boxes challenge partner, i see you there.

Some of your works are good you have to improve

Lines

They are great especially your superimposed but after that your lines become wobbly as seen in ghosting and planes.

Ellipses

Same with the ellipses, they are wobbly. Try to strive in making your line straight or, they say, confident while using your shoulder. Don't repeat the lines of ellipses, twice or thrice is enough. This exercises aim to make your line smoother for the next lesson.

Boxes

The rotation is not applied in rotating boxes, especially when they get farther in the center. It is almost have the same VP. One tip in doing this exercise is to remember about the degree, once the box is further from the center, the degree will get narrower. It makes the illusion of rotation. Again, use your shoulder. Same with the organic, try to make your lines parallel.

Hi Dopong! Here is my review of your work.

First of all I agree with you that wobbly lines are an issue. Something you should focus on before moving forward.

Now, let's proceed step by step.

Superimposed lines look great.

Ghosted lines: this is where the wobbly lines start showing up too frequently. Confidence is the main priority here. Accuracy comes with time and practice.

Ghosted planes: I appreciate that you planned your dots for all the lines. Wobbly lines are still too frequent, even though there are some confident lines here and there.

Ellipses in planes: here again ellipses are fairly accurate but not confident enough. Also remember to draw through your ellipses only two or three times: https://drawabox.com/lesson/1/tablesofellipses

Tables of Ellipses: confident marks are more frequent here and the orientation of the ellipses is consistent.

Funnels: ellipses are well kept inside the borders and well oriented through the common minor axis, but the wobbly lines undermine the overall effort.

Plotted perspective: neat and clean.

Rough Perspective: this is good and the linework starts showing progress toward the end.

Rotated boxes: well done. Boxes are well nested together and they comfortably rotate in space.

Organic perspective: this also is good. You'll have plenty of opportunity to practice perspective during the 250 box challenge and I'm happy to say that lines are fairly better.

Now, I want to be sure that those confident lines are dominant compared to the wobbly ones. We're not aiming toward perfection, absolutely not. Mistakes are expected and totally normal. I just want to be sure you're on the right track so you can get the most out of the 250 box challenge.

To start, read this lesson one more time: https://drawabox.com/lesson/1/ghostedlines

Then I'd like you to do one more page of ghosted lines and one more page of ghosted planes with ellipses inside the planes. The focus must be on confidence, not accuracy.

For every single mark, take all the time you need and be sure to:

rotate the canvas so you are in the most comfortable position

draw with your shoulder

carefully ghost your lines

then commit to your line without skipping a beat, fast enough so your brain doesn't get in the way

I agree with everyone in that your super imposed lines came out great! I find it interesting that after that, your lines get wobbly considering how strong your initial lines were. I know something that helped me is, I do really good with being super straight with short lines but... as they get longer...well it goes to pot. Learning to draw from the elbow was good for me, but anything that was longer than that reach really messed with me. learning to draw from the shoulder was weird to me. something that helped me was doing shoulder and arm circles as in exercises. Doing this limbered up my arm cause otherwise I felt stiff and awkward. so kind of doing some arm exercises and practicing moving my hand just at the wrist, locking it, moving from just my elbow, locking that and then moving only from my shoulder helped. it was a different type of movement for me to learn, moving from the shoulder....so practicing the movement without actually drawing helped me figure it out a bit and be more confident. hopefully that's helpful for you too! looking good!! keep up the practice!
