This is one of those situations where clicking on the image to see a higher resolution view makes a lot of difference. It brightens the shadows and gives better contrast in those subtle colour tones.
I think this is a nice capture, but it needs editing. if you look at the histogram, you'll see that you have a good spread of tones, but there is a lot bunched up at the bottom. I did a very simple edit, brightening the shadows and the lower midtones and cropping a bit. Not a good edit, but it shows what I mean.
