En Plein Air Miniature 4x4 Acrylic Paintings

A few of my plein air paintings from 2019. I was experimenting with acrylic on gessoed panels. The last couple of paintings I switched to 'open acrylics' to give myself more working time than regular acrylics. But even that proved challenging on a windy, dry day outside. Inside the atrium there was usually plenty of humidity which made the process easier.
