1,2 and 3 point perspective tutorials 2

I found more tutorials on Youtube but found it hard to find exercises that were new. I have completed both basic and challenging tasks to really get used to 1, 2 and 3 point perspective. In the basic drawings, it is easier to see the points and lines of measurement and shows my understanding of how to draw accurately using them as a guide. The other drawings are more built up and I became confused to which lines I was drawing to so the perspectives are not accurate but completing more tutorials with help my drawings to improve.
