What I've noticed about the lighting is getting the color just right combined with the blend mode. What I did was to make a brush for the fireplace lights, the angled things. Stamp a bunch of those down in any color. Set the fill to zero then fiddle with the color overlay layer style...I used a medium orange set to screen and then turned the opacity down. The torches were just a soft round brush. Then I blurred the whole thing to soften the edges. On a new layer I made the lighter colors that are closer to the light source for the fireplaces and torches, a light yellow-orange, and then set that to screen and turned the opacity down. So it's all just 2 layers, one orange and one yellow-orange. After I put in all of the lights I had to darken up the outside stuff cuz who runs torches and fireplaces at noon? Just didn't look right so I made it a night scene and that helps to set the mood.
