The first one has a 'softer' look to it. It looks like a watercolour painting which is quite nice.
The second one looks darker and unfortunately duller. The darker lighting means the soft quality of the coloring causes things to 'fade' out and attention drawn to the wrong things. Example, the roundish trees with the whitish tops. The whitish/greyish tops now stands out more than its olive green color making me think of mushrooms rather trees.
I think thats also the reason why the roofs now looks too bright? The whites now stands out more in the darker lighting giving me the impression of it 'glowing'.
While i really like the soft coloring, i guess once lighting comes in, the color pallete needs to be changed slightly to give it some livelier colors and more contrast so that the details don't get lost in the shadows.
Just my 2 cents.
