tiles + cliff = nono, i dont liek idea of you using incorrect tiles for cliffs (if you didnt know, you have lol), it looks tacky, andi m sure ingame it will look very , just because
1> tile dont blend into 1 another
2> 1/2 of corners you used are ones which contain correct tiles,
otherwise looking nice, ill post a preview of mine ina min XD, altough its nearly done , only need Tree's lol
