I am agreeing with the person above, because if you want buyers you will need to make some BIG improvements.
Tips?TBH your building needs a lot of improvement. It is to simple. A spawn point with four direct little roads with trees. You are heading in the right direction.
Ponds and houses...? Thats it? It has one pond, and houses someone else suggested...Make it like a medieval type? Add more things that will attract people IMO Ponds, Houses (but like a medieval type or a crazy house). I don't really SUGGEST making it bigger, because I am sure Server-Owners don't want complains on how laggy the spawn is, and same thing with more hills = more blocks = MORE LAG. So IMO that's a big no, no.
