Alright, this a pretty decent submission but a few things i wanna note - also, dont sway your hips, just your shoulders

lines q - the overshooting/missing the mark is perfectly fine, we prefer that quality over wobbly lines because it will go away as your muscle memory builds up - 250 boxes will give you plenty of practice on getting your lines right, so dont think about it too much

ellipses - your ellipses are still too wobbly, showing your too focused on having them being accurate rather than aiming for smooth, confident, and even shaped ellipses - just focus on this in your warmup, dont worry about focusing on finding the balance as more often than not you'll just get wobbly lines. instead focus on having them smooth and confident, and let the accuracy come as the muscle memory develops over time

rotated boxes - your gaps need to be consistent and narrow, meaning your boxes adjacent edges need to be right up next to eachother - you also need to be making sure they rotate with each box outwards from the center, https://drawabox.com/lesson/1/16/notrotating

-organic perspective was quite lacking, and you need to keep in mind to do just as many of each exercise as told, around the amount shown in example pages

overall though, this is a great submission! you did well to get through, and you have a good mindset going not to overwork and instead to get critique, good job!
