There is a few things im seeing that is weird.
1. The highways have bus stops and brick roads if i can call it that, JUST the brick road is blocked by the bus benches and sign
2. THERE are signs everywhere in roads in grass i mean everywhere.
3. The Highways can be cleaned up better the Pillars that holed up the highway can be connected better.
You have potential but needs some work, Keep up the great work.
