You did a good job on the challenge overall.

I can see you made some good improvement with the quality of your mark making. Your lines steadily become straighter and more confident looking as you progressed through the challenge. You also start to do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

Before we begin I just want to mention that in the future, when you go to scan your homework submissions, it would be better to scan your homework using the "photo" setting instead of the "drawing" setting. The drawing setting tends to up the contrast on an image and can cause you to lose some of the subtlety in your line work.

While your mark making has improved, I do see that you still hesitate in some areas. This is likely due to prioritizing your accuracy over creating a smooth, confident looking line.

Just remember that the confidence of the stroke is far and away your top priority. Once your pen touches the page, any opportunity to avoid mistakes has passed, so all you can really do is push through. Hesitation serves no purpose. Mistakes happen, but a smooth, confident mark is still useful even if it's a little off. If the line is wrong, we leave it and move onto the next step. Accuracy is something that you will improve on as you continue working through Drawabox and practice ghosting.

Now, while it is important that you use the ghosting method of each mark you make while doing Drawabox one thing you can try to help with ending your marks closer to where you want them is lifting the pen off of the page rather than stopping the motion of your arm. You can do this with extra line weight as well. I would also recommend that you read this comment by Uncomfortable, where he talks more about hesitation.

I can see that for some of your boxes you went back and tried to fix some mistakes. Remember that when you are working through Drawabox, you should not attempt to fix any mistakes you make. If the line is wrong, we leave it and move onto the next. I would also recommend that you read this comment by Uncomfortable.

I would also recommend that you try adding extra line weight to your boxes as an added step for your future warm ups.

When you go to add weight to a line it is important that you treat the added weight the same way you would a brand new line. That means taking your time to plan and ghost through your mark so that when you go to execute your extra line weight, it is done confidently and so that it blends seamlessly with your original mark. This will allow you to create more subtle and clean looking weight to your lines that reinforces the illusion of solidity in your boxes/forms. Extra line weight should be applied to the silhouette of your boxes. I recommend that you try adding your extra line weight in no more than 1-2 pases. This diagram should help you better understand how to properly apply your extra line weight.

Extra line weight should never be used to correct or hide mistakes. Something to keep in mind as well, when you are working through Drawabox you should be employing the ghosting method for every mark you make. This includes the hatching that we sometimes use for our boxes.

Some of your boxes were drawn a bit small. Part of the reason for the 5-6 boxes per page rule is so that students have enough room to draw their boxes larger while having room to check their convergences. By drawing your boxes very small you limit your own ability to execute your lines from the shoulder confidently, which affects the quality of your mark making. Drawing bigger also helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them. It isn't a problem if your line extensions end up touching other boxes on the page so long as the boxes themselves do not touch or overlap. This should give you enough room to draw your boxes at a larger, more useful size.This, along with varying your foreshortening and orientations of your boxes, will help you get the most out of the exercise.

I did see that you were checking some of your convergences incorrectly.

Checking your convergences is an important step so you should always take your time and make sure you are extending your sets of lines correctly. Noticing and identifying mistakes is a major part of the learning process. Checking your boxes for mistakes is how you know what areas you need to address so that you get the most out of each exercise.

Your line extensions should extend away from the viewer and towards their implied vanishing point. You should do this for all three sets of lines that make up your box. They should never be coming off of the center of the original Y that you use at the beginning of your construction. Be sure to visit the link for more information and for examples that you can use as reference. You can refer to the diagrams in this link if you are ever confused or uncertain.

Finally while your converges do improve overall I think this diagram will help you as well. When you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

Congrats again and good luck with lesson 2!
