Hey there, your English is great so don't worry about that. I'll be handling your 250 box challenge critique.
In your submission you're doing some things really well but there are some notable mistakes as well.
Your line work is really tidy and confident, no complaints here. It's great to see you're experimenting with line weight as well as applying your hatching confidently and patiently all of which are great habits to be building.
The key issues with your submission however are you're not utilizing vanishing points correctly and you extend your lines in the wrong direction quite frequently. Take a look at this example, it shows how each line in a set relates to one another. Our lines should always converge away from the viewer, you often mix this up and have your lines diverging which is what results in your boxes becoming distorted. When it comes to vanishing points you can see that each line converges consistently towards it, the inner pair will be fairly similar while the outer pair can vary quite a bit depending how close/far the vanishing point is from the box. The further the vanishing point the more parallel our lines become but they should always be converging at least slightly due to perspective.
Overall you're showing good progress just a misunderstanding of some of the important concepts that this exercise were meant to help you become more comfortable with. For that reason I'll be asking you to draw some more boxes.
It was a bit tricky deciding how many I should have you draw because your line work is so well done and you're clearly putting in proper time and not rushing. I don't want to risk you burning out but I need to make sure you grow more comfortable with these concepts moving forward.
I'd like you to draw 25 more boxes and submit them when replying to this critique, I'll go over them and move you on to the next lesson once you've shown you're ready.
I feel like this will give you enough boxes to experiment with, try moving the vanishing point closer and further away and think about how your lines will behave in response. Remember that they should always converge towards these set vanishing points. You'll find your boxes end up distorting a lot less once you start to accomplish this consistently.
I know you can do this, remember to take your time.
I look forward to seeing your work.
Next Steps:
Please draw 25 more boxes.
