Got a bigger canvas, which unfortunately was not stretched decently enough to try out a big painting. I didn’t want to trash it of course, so I took a chance and made a couple of other small wet-on-wet sketches. I had a reference image for the first 2, while other ones are totally from imagination (and I guess it’s noticeable!). Also, the new canvas (first 3 pictures) has a really nasty tooth which I don’t like at all.

 

Also, Nickel Azo Yellow seems to be mixing a bit better with ultramarine (last one), while lemon yellow appears to be too weak, losing its tinting properties when mixed with white (first and third).
