I started another fire escape scene last night. In the misfire below I used miskit/masque to block out the whites, but when I removed the miskit I thought 1) that I'd painted too much and 2) that, as usual, I was unhappy with the effect ... I could soften the hard edges I suppose, but I'd rather begin over.
Which I did, painting the scene above by painting around the whites. It's not very "readable" at the moment, but I think I'll wait and think about what to do: whatever I do I feel it shouldn't be much.
