Yeah these are good. I was thinking the same thing as Arcana regarding the shadows but then when I read what you said about the tool having them built in that explained it. The only other thing I was thinking about was if you could bring it into Gimp again and use the dodge/burn tool to add a little more 3d effect on items like the coal piles it might give some better depth. The stacked barrels and chests look a little flat. Bottom line though it works just fine as it is and anyone playing on it would probably not even look at this stuff because they would be on edge because the place seems abandoned and dangerous.

I may have to check out this tool as well because who isn't a free-gan?
