You know, I was thinking about how you needed to push your dark areas. But I never mentioned it because criticism is a hard thing. Plus add the internet and it could all go wrong. Mostly I with held because I see these for the exercises they are. My mind can't but help leap forward to other things you could be doing. Like line weight but like I said, that's jumping ahead. Just curious, what's the highest number B pencil you have? From what I've seen so far, my guess would be 2, maybe 4B.
