Some more negative-space practice. Again, I used my pencil to assess the angles and proportions. I’m pretty happy with these.
Note: The headphones were lying down on the table just in front of me.
And for the next one, I was working more on dark and light lines to indicate where the light source was. That was tricky, though, because there was more than one light source (as you can see by the two shadows), but the main one was on the right-hand side.
I over-complicated things by adding shading. I was trying to imitate a varying dark and light pattern across the jug (in its design), but that didn’t turn out very well. The jug was also quite far away, so I found it hard to assess its proportions.
