As the subject says, I've been in tileset development land for quite a while and I'm looking for some help. I'll put it all in spoilers just in case though.
As I've said in my Dream Stones thread, I'm building a series of tileset which doesn't rely on the black outline to indicate solids. Instead, I'll be using mainly atmosphere tricks to keep foreground and background separate.
The last 2 images demonstrate the atmosphere trick as best as I've done it so far. The first and second images are the original and a redo of a rusting industrial tileset. I'm stuck on it. I like the original, but it is too detailed and needs to be simplified.
Also, on the last screen is a demo of a tank builder and I'm trying to decide if image 1 & 2 would be better served by rusted out tanks than large non-specific industrial structures.

And if you REALLY want a spoiler, here is my giant forest tileset which I included 1. for bragging rights and 2. because I'm trying to decide on the yellow ground. I like how the outline is almost invisible until it overlaps with other ground so I can create cracks and overlapping sections. I did the same in the 3rd image above, but I thought I would include this one as well. The ground here will be almost identical to the ground of my wastelands tileset, seen with the rusting industrial tileset.

Thanks for your comments guys.
EDIT: Hmmm... imageshack looks pretty sucky. I may update this later and use a different service.
