Hello! I'll be critiquing your 250 Box Challenge this morning.

I noticed that many times when you tried to work with shallower foreshortening, some set of edges would end up parallel or diverge. A good example of this is box 166. I see some subtle convergence between the sets of red parallel lines, but the ones on the very left and very right exhibit slight divergence from the two in the center. Many times this is due to the position of the inside corner (which is to be expected) but sometimes is just due to how your edges are stationed in space.

For boxes that are closer to two point perspective, such as box 18, you tended to converge to two vanishing points as opposed to one. For instance, by extending the blue convergence lines out into space, we can see that we get two different vanishing points that are across from one another. This occurs with many different boxes during the exercise, and it's a common issue across many people's work. Just try to push those vanishing piints closer together, or do some rough eye measurements when plotting lines to work towards proper convergence.

Moreover, when you tried to push towards more dramatic foreshortening, you ended up squeezing some angles down to being less than 90 degrees, like for box 73. This will cause a fair bit of distortion and may make finding vanishing points a bit more difficult.

However, I noticed that many times you drew in two-point perspective or one-point perspective. Some culprits included boxes 39, 46, 47, 53, 54, 95, 106, 132, 139, 141, 148, 151, 156, 173, 177, 204, and 211 for one-point perspective and 20, 26, 25, 31, 34, 75, 79, 102, 163, 181, and 200 for two-point perspective. Practicing these other forms of perspective is great, but the aim of the 250 Box Challenge is to draw boxes whose lines all converge (https://drawabox.com/lesson/250boxes/1/reminders). I would like you to draw 25 more boxes in three-point perspective to remedy this. Keep in mind that the model for three-point perspective is a corner that faces the viewer, while two-point is an edge and one-point is a face.

I'd like to add, though, that when you drew in three-point perspective, you did great! Lines were confident and thoughtfully placed, and I noticed pretty regular convergence to a vanishing point. Overall, great work—I just want to make sure that you've had enough practice with three-point perspective and can really nail it.
