Just practicing my cloud structure a bit. I suck at doing really structured-looking thunderheads, so this one I picked a thunderhead off Google and paid close attention to the structure.
Here’s my ref:
As you can see, they have a really firm structure to them, with the big thunderheads in the center with the clouds lower down supporting them. The trouble is, I have trouble identifying the shapes in clouds like this, so I can’t keep them in my head long enough to transfer them to a painting. So my clouds tend to wind up as weird, vague shapes.
