Last night I decided to practice drawing water again. I tried drawing an ocean wave and the surface of a swimming pool. The latter never got past looking like an abstract blue field with white and dark blue squiggles, so I won't burden your eyes with that.
However, here is my ocean wave, which I am pretty happy with:
The part I was most nervous about, the seafoam, is the part I like best. I think I need to do more work on shading inside the tube of the curling wave, and I think the yellow highlighting looks a little bit too bright, but on the whole I am pleased with this in terms of progress.
