you have to understand something
these quick watercolor sketches were done in plein air, obviously. Plein air does not mean landscape, it means outdoor. It implies Alla Prima technique.
Do you also want to ban architecture, houses in landscape and close up of villages, flowers, people in landscape? what else is an inconvenience to you?
I really would like to see your work before you hit other artists who work honestly within the guidelines.
Good day and get out there do it yourself, we will see . Then I will salute you.
