oh, I love these! What are you carrying with you for these miniatures? I imagine tiny tubes of paint and a set of small brushes, a mini-palette, and small jars of turp and medium. What are the colors you're using?
I like the snow field one best, because the light is much crisper. The other two look about equally hazy, like it was really early in the morning, or just cloudy that day, and many colors are on the same level of brightness and vividness (is that a word?). Hope it wasn't freezing out there?
Wish I can go do some plein air too. It's been years since I last done so, and I miss it very much.
