Here are my level 1 attempts.

Thanks for the feedback, I have tried again and made the darkest value darker and the middle value darker, but I think the darker values (3 and 4) are now too similar. It's really hard!

Level 1 I used 2H, HB, 2B, 4B, 6B and 7B. I tried the markers as well but only had CG2, CG4, CG6 and Black, and it didn't work very well, especially in the lighter range.

After doing level 1, I also tried level 2, which I agree is harder.

These are my level 1 attempts. I found it tricky at times, but I think I got better at it.

Here's my level 1 submission. It took me some time to get used to drawing houses because I haven't really done that before, but I enjoyed it and feel like I've learned a lot.

I am slowly catching up. This is fun and I hope to do more of these.

Level 1. Feedback always appreciated.

Level 1

I have spent a lot of time on this one and have been frustrated that so many of my wheels look flat. I'm not sure if it's because my vanishing points are too close together because my construction seems to be right as far as I can tell. Maybe my estimate of a square in perspective is not very good. I would love some advice on how to do that better. The only one I'm ok with posting at the moment is this one, but I did use a ruler because I wanted to make sure I was accurate. I will have to keep practising and if anyone can give me any tips about how to avoid flat wheels I would appreciate that.
