It's way too dark, I have to get really close to my monitor to see what's going on. Besides, esp. when I look at the first screen I think the black background could use some work. Maybe you can make it as a dark circle gradient with low contrast and its "bright" spot in the center (that is covered by the map/ room), then tint the gradient by the average color of the map's tiles? I am thinking of something like http://en.wikipedia.org/wiki/Ambilight.
