Hello! Let's take a look at your boxes.

You seem to have put a lot of thought into your boxes, however there are a couple of things to look after. The first couple of boxes have the extending lines facing the wrong direction. Remember that the the lines have to be extended away from the viewer, as lines that face the viewer don't extend to the vanishing point. Try extending the lines away from the center dot of the Y. You might also want to recall the previous steps in constructing the box as well.

Many of your extended lines are parallel to each other. A box in three point perspective will always have their lines converge, so they shouldn't be parallel. I know it's a bit tricky since we can't mark the vanishing point, but you can approximate.

As with the lesson 1 assignments, remember to prioritize confidence over accuracy when it comes to lines. There was some repeating in the first boxes, but you did show improvement with your later boxes. Keep it up!

The orientations of your later boxes are too similar. To differentiate, try doing different lengths for the lines of your Ys.
