The contrast between the tree and the grass is odd, and there isn't much detail to the grass. I am pretty sure I have seen that treetop before I just can't pinpoint where. The perspective on the roof border is wrong. Detailing on the bricks look weird and the wooden bar above the door looks out of place.

Edit:

Also because you said it was a medieval server, the bricks, the window, and the door handle look out of place.
