Looks great! I never did plein aire painting but I too have done plein aire sketching.
Lot less to drag around with you and it is ready to go at anytime the mood strikes you.
We are having unseasonably warm and dry weather here in the Pacific Northwest. Yesterday was a good day to ignore garden chores and goof off with my sketchbook in the yard. I’m taking the Realistic Pencil course and enjoying the portability of graphite.
