Lol @ Gaia Online Avis.I was not expecting that, since I have an account there.
But I like it Just one, maybe two things.
1.The Policeman sprite shouldnt be inside the cave hole, instead, place him in the space in front, so it doesnt look so...wierd.
2.You probably dont know how to do this so I would leave it alone, but the kid floating above the grass.If it is possible, place him infront of that tile if its a trainer or if he is just an info guy, place him infront then face him towards the grass.
Other than that, it looks pretty decent.
