I'm not one to collaborate, but to elaborate on what I said before, like my character Azalea says in Shadow of a God-King, getting the shadows right is so important. My beliefs about this is that it's the contrast between light and shadow that really bring an image to life, and everything else can be trash and the painting or drawing can still be good if you get this right.
I know it's an obvious and simple concept, but like a decade ago I was in a passenger seat as we drove by some grass, and I finally really saw what I was looking at, and recognized on both an intuitive an analytical level the drastic difference between the grass in the shade and the grass in the sun, and how that made it look so incredible and beautiful.
Like I said, this is captain obvious stuff, but for whatever reason so many people fail to attempt to duplicate this when they draw or paint. They tend to create these symbollic representations of what they see, and really it's what their mind interprets, because what they actually SEE is a lot more dynamic in its range of tones and colors.
So, you did a pretty good job on that aspect, and it's very important to the image. I won't offer suggestions to improve it, but I will say to always remember that the LIFE of your artwork lives within the interplay between light and shadow.
