Come to Florida
This morning I checked the weather for the town near Boston where I lived until 3 years ago. It was -10 deg F. A couple of hours ago it had reached all of +10 deg F. Here in Sarasota it was in the low 70s for most of the afternoon.
Time for everyone to come to Florida for a few days. You need a break.
As far as the drawing is concerned, I tried a different black gouache – W&N Ivory Black. It took a lot more of it to get the same deep black that I was able to get with the other one, so I would imagine that it would ultimately cost more to use. I also used a couple of Faber Castell PITT markers to get some additional tone. And the Pro White ink for highlights.
