Hi there E! Welcome to DAB! Awesome to see your enthusiasm, I'll be critiquing your homework today and I'll give you some pointers to work on;

On linework;

Some of your lines are able to shoot straight and confidently, and based on your prioritising of confidence over accuracy in the ghosted lines exercise I think you've understood the base concept that confidence >> accuracy. However you do seem to struggle with putting this into practise, as quite a number of your lines in the ghosted planes exercise have problems with wobbling and course-correcting. The most common place I see this on your line is near the beginning of the line, where you push through the line initially but lose confidence as you try to push through on the line, hence you wobble for a moment before you course-correct and push through with the rest of the line. This is a problem that I would have when I did my lesson 1, as I'd ghost through the motion multiple times, but as I put my pen to the paper I'd lose the confidence of the ghosting motion I'd practised before the line. The best way to correct this is to diligently get those lines down with the same confidence as your ghosting motion, treating the two no differently. Keep practising and you'll overcome the admittedly quite daunting quality that clean, pristine, unmarked paper has. The other place I notice the wobbling is near the end of your line, as you push through the mid-section, but then your brain realises "oh I have to stop soon", which causes you to hesistate and wobble as you're split between continuing and stopping. The best advice I have to correct this is to determine where you're going to stop before you draw the line. You ghost through the motion with the confidence of "I will draw this line straight, in this direction, this much, in one singular motion". You won't get it right with the accuracy, you'll likely over or undershoot, but you'll have it set in your mind that you will draw the line in one motion. Again it's a confidence thing that you'll need to work through with practise. The good news is that it's an easily rectifiable issue as long as you're aware of it, and as long as you put in the practise to improve your confidence and lower your anxiety.

One other point to note is that your line confidence (and general smoothness) is severely diminished throughout the box exercises, as they begin to wobble significantly throughout the whole trajectory. This is not an uncommon mistake amongst beginners, especially so on those who struggled more on linework. It seems to be the case that the additional requirements of "draw a box like this, think about the vanishing points, make the lines converge, make the boxes rotate, make them vanish in perspective" overwhelm a majority of students, and as such they get caught up in the exercise's additional requirements and lose sight of their linework as they get more anxious about "getting the line wrong". I gently stress the importance of prioritising confident linework above all else as our unholy art god whomst we must pay heedance to. It's important to remember the importance of keeping our lines confident and smooth, as without it any drawing we make will struggle to look as good as we would like it to be. Confident linework is a fundamental pillar in this respect. Even when we're tackling complex tasks, such as drawing boxes, or plants, or insects, or....whatever. We don't want to lose sight of our linework as we get caught up with these additional problems, as we'll end up being stuck drawing wonky boxes, plants, insects.. etc. Don't worry about the line being "right", focus on getting those lines (or ellipses) confident first. We'll deal with getting them in the right place later.

On ellipses;

Ellipses are looking fine so far. You're understanding and applying all the concepts, you just struggle to really nail the smoothness of the ellipses that we're aiming for. This is completely normal, I see this a lot with beginners. It's an issue that you'll overcome with enough practise, as it's purely an issue with muscle memory. Note the wobbliness and deformation of the draw-throughs, especially as you try to make the boundaries of the ellipses conform to their neighbours. My recommendation for you is to pay close attention to practising ellipses in your warm-up sessions. Ellipses in planes would be particularly good as it allows you to practise linework also, but I would not neglect ellipses in tables as that allows you to practise a wide range of ellipses quite easily. Focus on the confidence, trying to smoothen up those ellipses, and then try to tighten up the draw-through's and make them less loose. Once you're feeling confident here, I highly recommend you incorperate the funnels exercise into your warm-ups more, as that'll help develop your skills further. On the funnels exercise you're making the following mistakes primarily; https://drawabox.com/lesson/1/14/notaligned, https://drawabox.com/lesson/1/14/loose . These are common mistakes, especially for beginners, but they're worth pointing out regardless.

On perspective;

You did really quite well on these perspective exercises all things considered. As seen in your rough perspective exercise, you're able to understand the main conceptual idea of vanishing points and convergences, and are able to judge them with some a relatively decent degree of accuracy. You struggle with achieving the full degrees of rotation, in their specified quantites, on the rotated boxes exercise, and you have difficulty keeping the overall sense of perspective in the organic perspective exercise as you fail to keep the foreshortening of your boxes consistent in the scene. https://drawabox.com/lesson/1/7/foreshortening.

These are common errors, as these exercises are expressly and specifically designed to throw you into the firey pit of art failure. They're designed to push students beyond their current limits, exposing them to concepts and challenges that they very likely will not be capable of completing. I put these critiques of your perspective exercises primarily in the interest of thoroughness, but also as a reference point for you to revisit later. Once you complete the 250 box challenge you will have a significantly increased mileage for developing spatial awareness and understanding of 3D space. These critiques will likely click with you better at that point, and it may be worth your time to re-attempt these exercises with your newfound knowledge. You may still find them just as hard as you did now, and that's okay too.
