It's better, but I feel that the colour is off. The greeny-yellow light isn't working very well with your hay (which is lit beautifully by the way - the best lit hay I've ever seen). Have you considered going with a sinster rusty-coloured light inside the sewer, so that the dominant colours below the grate are reddish-orange and black? This might help to differentiate it from the yellow hay; you would probably want to change the orange colour of the light source to the right in that case however.

In any case I love it, and i might even use it in my campaign next week!
