Hi Emirmdd, good job on completing the 250 box challenge. This is no small feat and you should be very proud of yourself. You made some good progress throughout in terms of your sense of space as well as your overall line quality. One thing I do want to point out is in regard to your hatching, you could definitely have been a little more patient with each line as they are not making contact with the edges of your planes. You did a good job applying your extension lines from page to page and using the information to help guide you in subsequent pages. You also did a good job varying up your box sizes and rates of convergences.

In terms of your converging lines, you did a pretty good job in trending towards having your lines all converge to a singular point by taking into account all of the parallel lines and not focusing too much on a back corner or any other distraction like that. There are still a few skew lines so I will post this infographic that uncomfortable has made. The key take-away from this is how we view parallel lines in perspective as an ensemble and need not worry about anything else. Often times students will focus too much on trying to make all the lines meet up in the back corner instead of focusing on keeping all the lines tracking towards their shared vanishing point. You have done a pretty good job with that though so it's just a matter to keep in mind as you continue practicing your boxes.

One more thing I would like to point out is your tendency to redraw lines that you are not happy with the first time around. Remember that one of the reasons we draw in ink is to respect line economy and learn to plan our lines and live with the results. Redrawing lines only adds visual clutter and draws more attention to areas we'd rather not be looked at very closely. So always remember to plan your lines, prepare and ghost them, and only execute when ready to live with and work with the results. I want to specifically commend your 250th box. Drawing large boxes is a completely different task than drawing boxes at the average scale you were and you managed it very well. It really highlights what the infographic talks about, in my opinion, in terms of the angles between the lines and their relation to the vanishing point.

So with this your 250 box challenge is complete. Congratulations again. Make sure to keep boxes in your warm ups once in a while so you don't get rusty as lessons 2-5 are a lot more organic based with not many boxes and you don't want to be rusty by the time you get to lesson 6. Keep up the good work.
