Just because you can detail grass with those tiles doesn't mean you should use them for filler, personally I'd rather look at open grass than the below unless they're arranged in some sort of appealing pattern or grouped with certain tiles where it makes sense to use them.

The sand path could look a bit better if it was evened out but they're weird but I have trouble myself trying to get them to look good as well.

The bricks should be used to outline a path or point a player in a direction, using them as random filler doesn't work well.

Other than that I like the Inside/Outside context.
