Crown flowers - labour in painting

This is only a small painting that is slightly bigger than a postcard. I was trying out the Artist acrylic paints that I bought over the weekend using colours that I did not have before. Layering the paints from dark to light and trying to play around with different strokes and colour application to get a result that I could be satisfied with, I went from acceptable to overdoing the white highlights. So of the whole series documenting this particular exercise, I like the second last painting best.
