Michael's studies of two kinds of clover...
It takes time to work out how to paint something so it's wise to make small studies and try different approaches and work out some challenges.

It all takes time. Slowing down and spending that time with your subject is the way to uncovering its secrets and coaxing it into showing you how to paint it well.
