Somehow I managed to finish it today. One of the legs is a little too bright, and I thought the hip joint mobility was dead because I'd assembled the joints backwards, but again there were a few issues, but it's finished.
This time I went from black primer to macabony → ochre → matte clear.
It's a pain, but masking is very useful for differently painting the shoulders and giant shoulders.
When lining the left giant shoulder, I wiped it with enamel solvent, and it smudged a little. Oh well, it's a horse mackerel, so it's okay. It looks burnt, so that's fine. I'm not chasing perfection. Completion comes first!
In the photos up to this point, the hip joints are attached backwards, so the legs are generally off to the front
