Overall a fantastic piece of work, my only criticism with this painting is the heavy dark background. I think for you to make it work, incorporate deeper shadows within the still life so that the objects don't overwhelm the viewer with too much light. Take a look at Caravaggio's work, and his over dramatization on chiaroscuro. All in all it does create a visible contrast and a great piece that's extremely well done. I'm working on my critiques so let me know if this was at all helpful, or if I'm completely off the page on this one. Again I'm not one to criticize because this is amazing, I just want to see if this is helpful at all.
I love the colors and textures. It's all very rich and ponderous and solemn, even. I think it's the black background that makes us stop, and look, and consider, instead of glancing quickly, then leaving for something frivolous. You really showcased the overlooked beauty of natural things, not only the vegetables, but also the wood and the bowl. They say, "See what care went into making us, and it was all for you to enjoy. Don't pass us by."
