Your line excercise look really nice, there is flow and cleanliness. Your 2 point perspective is also very accurate, but it looks like you struggled a little bit with one point perspective. It looks to me like your 2 point perspective was made with a ruler and 1 point perspective was made freehand because the perspective is really off and the lines are wobbly. Good job overall. I have not gotten to the other lessons but I hope this feedback helps.
