Cow and Calf at Twilight

I started thinking about the evening light as soon as daylight savings ended a few weeks ago. I have never painted an evening scene so I tried this cow and her calf in the twilight and found it challenging and fun at the same time. I'm constantly going back and repainting certain areas that don't seem to work. I've done this so many times I think I should just start a whole new painting using the night time light.
