Shawn, like I said on aim. You should try a whole new tileset and use the "type 2" tileset (e.g look at umm Era)
It allows you to have more tiles and alot of other stuff. Ontop of that your a good graphic artist but you should just try a whole new thing cause mmmm.. I dunno like some things look out of place.
Like see the bridge, the image is nice and smooth. (atleast in real size on the server) You should try to bring that smooth ness and possibly the same kind of pallet to more tiles.
You should possibly try a new grass to water tile aswell, I saw the tile on Fairylands the type I'm talking about. ->

Contains an example.. but I can't find any good screenshots. Its basicly more like "rock/grass to water" and than the water is semi transparent for a while until it just takes up one patern, and its animted
wich makes it look good
(By the way this was a positive comment :P so don't come chasing me with a ak47 screaming DIE!
