Hi UNCLOUDED, I would like to give you some insights that you could find helpful in this lesson:

• Superimpossed Lines:

  Good job!!, these look very good, but I can see that your lines arch a bit here, maybe you can fix that by first drawing a line with pencil (very slightly to not to carve the paper) and use it to superimpose the rest of the lines, so you will have a straight guide for every line done with ink. Can do the same with the curves, but this is a pretty good start.

• Ghosted Lines:

  These looks good, but I fear that you are being a bit shy when you draw these lines. I would like to see more lines and of different size, ones of a few inches and another as long as the width of the entire paper. Don't fear to overlap them in order to draw a diversity of angles and sizes, and of course remember to rotate your paper.

• Ellipses:

  These looks good too, but I see that you are getting some angulous turns in your ellipses. Remember that the key here is ghosting, so, if necesary, ghost enoughly to get the feel of a natural ellipse in your arm (thats how muscle memory works), once you do the mark, you will note how your ellipses come natural and curvy.

  Don't get too worry about filling every little space with tiny ellipses like in this screenshoot: https://prnt.sc/w135jv that will make you pressured for put a lot of ellipses that very probably will look plane and unnatural, because you will not have the sufficient space to draw them well.

• Planes / Ellipses in Planes:

  These are very good, but keep an eye on how many times you re-draw over the same ellipese. Remember that ideally, you should do 2 loops, but 3 are the maximum.

  The woobliness of your curves here will get aliviated when you get confident by ghosting properly your ellipses.

• Planes:

  My only objection here is the alligment of the minor axis with the main axis line of the funnel, see the difference here: https://prnt.sc/w139s3 As you can see, the minnor axis of your ellipses should be alligned to the "Y" axis of your funnel, as the mayor axis of the ellipses remain perpendicular.

  Your can try this too: https://drawabox.com/lesson/1/13/step3 in order to make your ellipses more "3Dish", by making every adjacent ellipse to an earlier one more wide, but entirely optional after all.

• Plotted Perspective:

  Looks good but evidently you got shy or maybe even tired of the exercise after a while, try to rest a bit if you start to get bored of these exercises because doing them in that state could hinder your performance. Try to draw more boxes of different sizes and forms the next time.

• Rough Perspective:

  Here we have some serious problems. First, you aren't finishing the construction of the boxes: https://prnt.sc/w13egp Second, you missed the point of the exercise completely, because you are pointing actually the vetices of the boxes to the VPs, not the sides as it should be. This is what you shoud have done: https://prnt.sc/w13g73 Finally, Your lines don't converge to the vp of the horizon but get lost in it each one on a differenth "path", so I seriously recommend to re-study the perspective theory on the article and redo this exercise, not to perfection of course, but only one more time, after you understood the rules of it.

• Rotated Boxes:

  Good job here, its a pretty good attempt!!, but you have the classic error of a beginner here, which is that you aren't rotating your boxes, but making them smaller: https://drawabox.com/lesson/1/16/notrotating You need to keep in mind that a box is rotated when the VPs rest in the horizon moves from their original position, maintaining the distance between them: https://drawabox.com/lesson/1/16/rotation That is how you rotate a box without deforming it, maybe you should do warmups of this one recurrently.

  This is another point that deserves attention, these boxes aren't cubes but "headless pyramids": https://drawabox.com/lesson/1/16/step4 that is how they fit toghether to give that appearence of a sphere made with boxes, by alligning them each other.

• Organic Perspective:

  Looks good... but its kinda the same point of plotted perspective... you certainly aren't putting your max effort on these... Rememeber the motto of Draw a Box: At the Best of your Current Hability, so if you are getting tired of the exercise, just rest for some minutes and then go back to it with renewed energy.

  You can try to vary the size and forms of boxes here too, in order to force yourself to draw these boxes in different angles (remember to rotate your paper as you draw in other angles than the usuals) so you get more and more experienced in this exercise.

  Remember that you can overlap your boxes a bit, like in this example: https://prnt.sc/w13ov3 so your boxes will look more natural and "cinematic", like as they arecoming in a parade from the center of the galaxy to where you are :D

  A note about Warmups: for every exercise you correctly have finished, use them as a warmup: chose one or two of them and do them for no more than 15 or even 20 minutes... and change them everyday. For complex exercises like the Rotated Boxes or the Rough Perspective, you can do just a quadrant, like this: https://d15v304a6xpq4b.cloudfront.net/lesson_images/71381f82.jpg or just a segment of the grid of Rough Perspective.

  Thats all, hope it helps!!
