Inktober 2020 prompt#3: bulky

It took me a while to figure out what I wanted to do for the "bulky" prompt, and it was the last of the first 8 I drew in one day.  Eventually I went with an idea I'd suggested to my friend when she was looking for inspiration, but she chose not to do this idea.  I googled images of whales and this was one of the first I came across, although the original photo had 3 divers at the surface.
