When you are painting on larger sized canvasses, it takes a lot of paint, and sometimes a lot of patience. I do not paint in the style of some acrylic painters where the paint is thick and covers the canvas in one stroke of the brush. Instead, I use many, many layers of glazing of the paint to achieve the transparent look and "glow" of my paintings.
I consider this painting to still be in the UGLY stage, although it is progressing through LESS UGLY to the I'M GETTING HAPPIER stage. I'm going to leave the petals for now and focus on the leaves, so the next time you see this painting, it will look much better - like a sick patient who is on his way to health, but you can tell he isn't up to his usual self yet.
