Thank you very much for the thorough critique, Rob! :D

I will make sure to build a warmup routine that helps me improve on those areas where I need improvement.

As for the boxes, I know what you mean with some of them. Some times I feel like I got it in my mind, but overall I feel like I'm not quite understanding them, so after the 250 box challenge official instructions, I will also take a look at the various notes on Discord that people shared, so I can really grasp this and draw 250 pretty boxes yay!

Thanks again for the encouraging critique and good luck with the rest of your work!
