Mathias: I realized the shadow was a problem. I was wondering if I should add a shadow to the sprite, and I guess I should at least try it out. Who knows? Maybe it won't look half bad! But I agree about the murkiness...I was trying to make him look all rough and explorer like, so i didn't want him to be all happy and cheery in his attire choice, and also I don't want him and the grass to be too bright together. So I guess I'll be playing around with that some more.
Jakerpot: Here are those tiles:

And also, just a side note with that, it has the road I made in there. so feel free all of you to take a look at that!
That tile is actually bigger than just those leaves, but I'll try adding more depth/detail to that tile and see if that helps it look less...strange.
Kaelaar: I'm attempting to make the grass darker without making it too dull, but I'll have to see what it looks like with the sprite on top of it and it being a little darker.
