There were a lot of great color variations withing the light and shadow areas of this squash. One of the hardest things that I have found to paint is yellow in shadow. Sometimes it gets cooler and goes green or it keeps its warm hue and just gets darker brown, but to make it convincing enough it has to be properly subdued yet still retain the idea of yellow. I also enjoyed trying to get the variation of texture of the squash, texture is one thing that oil paint excels at.
