Chris,

This example is lovely. I love looking at your work.

I've posted the mirror question in a few places. I've received a great deal of good advice from Virgil Elliott's group. Basically as you have said. Follow your reference. Although there are no hard rules, remember that glass has a green tint, and this should cool down your colors that values are indeed tighter, lights darker darks lighter. Much the same we have heard. Indicate the light reflecting with hints and glints in the mirror's bevel.

And reveal your light source if the set up allows, washing out a corner. Which is what my set up will allow.

The tip about all glass having a slight green tint was very helpful, I had thought I was reading that in my reference, but wasn't sure.
I had is sort of aqua, which I' think I'll leave in this under-painting.

I look forward to more input.
