I agree with toning down the background but if you want to show a little bit more than Manfred's crop try only reducing the left side slightly to end up with something like 5 x 4 ratio?
With the second image, try increasing brightness on the midtones (brownish areas) while reducing the background brightness.
I would go even more dramatic in the crop and produce something like this.......
or this............
Perhaps you might try making it a night shot:

Thanks for all the suggestions. I do like the close crop as well as the "night time" shot. Very creative. I might also try the close crop but in B&W with high contrast. Or, maybe just go outside my normal comfort zone and be artistically creative and experiment a little.
