Basing a track for home on a real track, or the ones in GT on the PS2 can end up being large in the total area, but short in the length of track you get to race on. For me personally, the more racing track and less grass/scenery areas the better.
Things I think that make a good looking track. Advertising on Barriers, and in the places that real tracks plaster advertising (Bridges, signs in grass areas, etc).
Bridges – ones you can drive over are great, but you need to work out your angles really well before you start building. Also pedestrian bridges, tyre bridges. They add a sencs of 3d to the track.
Scenery – realistic looking buildings, trees and bushes look fantastic, but sometimes this can be expensive to add, or tricky to make.
Lights – set of starters lights at least.
Additional vehicles – support crew, trucks, ambulance, etc.
Thats my suggestions anyway
