So, after screwing around with my dirt tile for a while, i decided to do some looking around at dirt in other games (ultima online, diablo 2, world of warcraft, and some others)
...In my quest to find some decent looking dirt that I could slightly emulate, I journied to Hillsbrad Foothills in World of Warcraft (seeing as how the dirt I wanted to make pretty much has the same dark color as the dirt found there)...
ANYWAYS... while I was studying the boring dirt there, I noticed the grass as well, which seemed to look fairly decent.. So I decided to take another shot at making a grass tile, with a totally new approach... let me know what you guys think.

(I've taken a small poll from some friends & the few I've asked seem to like the other 2 grass tiles i made better... o.O)
Here's what I showed them & asked them which they thought looked more like grass:
