Tranquil but for the noisy cows

I am staying with my twin sister, and we've been doing some fun things: backyard golf, target shooting! and en plein air painting from her back fence. This was a view of distant farm buildings, interrupted by a run of cattle. They were bellowing as they ran though my painting!

(I'm experimenting with painting oil on watercolour paper. This was done without a primer, and therefore was absorbing the paint a little too fast. Next one I'll try priming first.)
