Hi there! You've done a p good attempt overall. Lines are clean, you're doing a good job applying hatching and you're applying the ghosting well too.
The main thing is that you've mostly focused on extreme perspective boxes and didn't draw many shallow perspective boxes. And the shallow perspective boxes that you drew I have a feeling that you were trying to make lines parallel and not converge, because they have a tendency to be parallel or diverge. All sets of parallel lines in reality (and not after being affected by perspective or being in a drawing) have to converge and get closer together, so they can't get away or be parallel.
Here's a step by step tutorial on how to draw a box with converging lines, so if you're confused about it give it a try.
Before moving on I want to amke suire you know how to draw shallow perspective boxes, as they're suuuuper important, so give me 20 more boxes with shallow perspective, I know it's tough to do more boxes but good luck! You can do it! Feel free to ping me in discord or ask here if you got any questions.
Next Steps:
