I don't think it is too low-poly; however the full-stone arch is somewhat odd. Each arch section (non vertical/horizontal) need to be a single block of stone - this will overcome the angular design - you can't have those sections built from small bricks.
Remember that point with low poly stuff - the smaller the bricks, the more odd it will look.
Of course it depends on his development PC and also the NPC's he is going to populate it with.
Visually it is overall good - but nothing special
