Oil and leaves on board

This next image is a work in progress, mainly drying time so I can add more leaves. Because my last painting was quite dark I wanted to lighten this one. Again using two shades, but this time red and yellow only, I spread the paint with thinner but left the paint quite thick in places. I added some leaves, more paint with some white this time, then more leaves on top. I want to build up the leaf section to depict trees stood together.
