I notice you have some nice looking shadows and lighting which leads me to a question. Is it better to leave that stuff off (except for natural lighting) or put it in? I know with Maptool you can set up line of sight stuff depending on light sources and as the player moves the areas he can't see are hidden from view. thus the torch he carries will put light upon the correct things and shroud other in black. I haven't decided myself which is better.

I admit that leaving out the lighting makes an image look less fantastic but when you can drop objects that are light sources into it within VTT does this create any problems?
