Hi, I'll be critiquing your 250 boxes challenge! First of all, congratulations on finishing this challenge! Hopefully you have learned about your perspective and enjoyed doing so!

Overall, I am pretty impressed with the confidence that you have shown in the boxes. The lines are straight and while at first I saw a bit of curvature, it would soon be eliminated in the later boxes. There was a variety of shortening, both shallow and rapid which mean you had the full experience of the challenges. Hatching is also done correctly (on the side closest to the viewer) and confidently as well. Convergence is visible on the line extension, meaning that you are exposed to what this challenge is intend to do.

The consistent problem I wanna bring up is the dreaded corner that was the further away from the viewer. The inside corner seems to just focus only around 1-2 vanishing points, causing the last vanishing poing to be skewed and ended up ruining the appearance that it is a box. This problem is common and I myself have made these mistake when doing this challenges, but I feel like there might be some fear when tackling this issue at the beginning. Around boxes 50 - 117, I don't see any line extensions coming out from the inside corner of the box on any of the vanishing points. I do note that this problem are fixed in the second half of the exercise, where you put line extensions on the this corner, but the problem still happens pretty consistently.

The official guide suggested that this happen usually because of overestimation on the VP. The guide recommended paying attention to the way the edges would meet (You can view the image here: https://imgur.com/8PqQLE0).

My personal experience tackling this, which you might take with a grain of salt, is that I essentially put a small dot on where I would think the inner corner should be placed to converge with one vanishing point. Do this for all three vanishing point and the area within the three dots are essentially a good estimation of where you should put the corner. The dots are light, like small taps from the pen. I visualize it here, but this is just my method and may not work for you. Visual guide is here (https://imgur.com/a/EIqWM1T).

Also, a small advice is to don't be afraid to make mistake in this corse. Don't be afraid if your inner corner is way off. We are here to learn! Mistakes happen and having a line extension from when things went really wrong might make it easy for us to understand where we did it wrong.

I can see clear better convergence as the challenge goes on, so I think you know that this is probably the thing you might want to pay attention when you continue throughout the lesson. However, I think that you have done all that the course have asked you to do and I think you should be ok to continue with the next lesson!
