Colin, I am echoing Karl here, the cubs are absolutely adorable and the images are gorgeous. The first image could be the cover of a storybook for children; my top pick. As matter of fact, it reminds me of one. YGMV!
The fox and the butterfly is a precious wildlife moment. That butterfly stands out like a bright light, and immediately grabs the eye. But then there is that beautiful fox fixated on the butterfly, without any concern to the photographer. Nice!
