I've done a few sketches of cows. They were really curious about me standing here. I like their shapes, nice planes, simple and expressive.
Cows, oil 13x23cm
Here is the last (old) sketcbook I found. I like the ring bound because I can change pages forever and choose and try different paper each time as well. It's small (5x3.5 in) but I can do landscape on both pages. Together with my tiny watercolor box it's very handy for quick color studies.
