This is a very good map, but I agree with Nuzamaki. The Pokémon Centre looks odd and inconsistent with the visual style of the other buildings, particularly the dome (which looks very basic and unfinished). Also, if this is using Essentials then the player isn't going to see the waterfall feature on the left, nor most of the water on the right. I would open up the rightmost fence, allowing the player to surf on that water - perhaps placing an item the other side?
Other than that, nice job, keep up the good work.
