Painting 20

I discovered these long canvases and wanted to explore the size again. This painting is from a photo from a trip long ago to Roaton, an island off the coast of Honduras. It was a magical place free of tourist and long on relaxation, empty beaches and cheap seafood. I have heard of tales that coconuts from these beautiful palms have actually killed people as they fall to the ground. I became as paranoid of that as I have been of driving with my window down for fear of something flying into the car and hitting my temple, causing instant death. I'm not sure if I was actually having this thought as I rested on this picture perfect beach when a coconut happen to fall from the tree I was lounging under and landed inches from my head. I'm not making this up. Those coconuts actually are deadly! I'm lucky to be alive. Honduras could have killed me for so many reasons, the coconut was just one. But I digress. The painting is nicely composed, but where is the light source, the shadow? What makes an interested painting. Variation of color, stroke, play of light. Play of light? What light? It's sunny cause we can see the sky, but we certainly can't tell where the sun is. I do think the main palm turned out nice. The painting is sentimental to me, and not horrible, but I question why I have it on the studio website cause I don't think it represents my best. Although it does look better on that site than it does here. But it will be coming done soon. By the way, now that I have 20 paintings, this brings me back to my instructor when she said, you get about 1 good painting for every 20. Which one is the good painting?
