Painting on Pink Ground

I’ve been playing with different coloured under paint recently. I got a bright magenta colour and washed over a few canvases before doing painting. I’ve also been painting pretty rapidly and trying to get better at one-session paintings.
This one I’m really pleased with – it looks hot and dusky and baked. Finally I feel like I’m getting the look of the heat I was after. I think the pink under painting really helps, it punches through the sky quite well.

Don’t know what happened when i scanned it in, got some gloop on the scanner. The gloop is not in the painting. I could pretend it’s badly rendered birds, but nope. It’s gloop.
