I'll be going back to this one; the combination of accuracy plus pressure is one I definitely need to work on!

Attempt #2, again pre-demo. This time I laid out my value steps more clearly, and I think the edges come through much better. Critique is welcome; I'm about to watch the demo video!

So I can already see that my values are off; not enough difference between the lower two lights, and the edges aren't sharp enough. Feedback is welcome, please!
