Hi, PandasEatBamboo. Good work going through this lesson.

Your superimposed lines are arching a bit. This can happen with you're not correctly drawing from the shoulder and end up mixing some elbow motion into your movement. Be sure to always draw from the shoulder. Your ghosted lines are better in this regard, but, when going through your ghosted planes, they could definitely be smoother. Don't forget to apply the ghosting method and draw each line with a swift stroke. Don't try to steer it into the end point during the drawing process. That's what the ghosting is for.

Your ellipses are very good, which is a sign you drew them with confidence. During the ellipses in planes exercise a few of them ended up being deformed, probably because you were trying too hard to make sure they would fit inside the planes.

The rough perspective exercise is very nice. You did what as asked of you and ended with a good perspective. Some boxes could be better aligned with the horizon line, though. Remember that the horizontal lines should be parallel to the horizon, while the vertical ones should be perpendicular to it.

You did very well on your rotating boxes, although some of them are not quite rotating as they are sharing the same vanishing point. This is noticeable on some of the boxes near the bottom left corner. If you had pushed the rotation further on the initial middle row/column boxes you might have prevented this.

The organic perspective is also good. You did a good job keeping the flow from the smaller to the larger boxes and ended up conveying a good sense of depth on the final work. You did well overlapping some of the boxes, but be careful when increasing the line weight of your boxes. This should be done just slightly and very subtle. The perspective is also decent in most of the boxes. There are a few of them which are not very good, but you'll have plenty of opportunities to get better at this during the boxes challenge.

One final note, though. Try to avoid correcting your lines by going over them. This happened in a few of your boxes exercise. If you misplace a line, just keep them in mind and do better on the next box.

Overall you did a good job here. Good luck for the other lessons.
