Great detail, beautiful colors, excellent bg and I like the rock it's stretching on. Never seen one of these critters in real life but I feel I could reach out and touch this one.
Lots of attitude from this little guy Jim I am picturing a mirror just opposite him and he is challenging himself. Nice captures of this little one, details are very pleasing.
I love these little guys - Pikas are too cute & as it turns out having a hard time with what's going on in Nature. They need help & that's what you're doing putting their faces on the web. Before your shots I had no idea they existed. Now I do & have found out that they're having problems.
