Your new tiles look pretty good. I like the first one more, though. At least you are making an attempt at using custom graphics.
By the way, you don't have to, but it would be nice if you replaced the tree from the last screenshot with something different. The only reason I am saying this is because it looks like the tree in Pokémon Harmony (I know that it is an indoor plant from FR'LG. That is why I said you don't have to replace it).
If you need me to make some custom tiles for you, you could just ask (Since my computer is down, so I can't work on Harmony and DarkDragon doesn't have anything for me to do).
