Your textures are looking good though you might want to make the basketball court's a little more subtle so they don't scream out at you like they are doing now. Less contrast... make the lines and grain a color closer to that light tan you got going on.
What template is this for? The RTP? Because right now it's a bit out of wack as far as proportions go like some many of the others have said before. The car is fine but it doesn't go with what you have here. And for a game like this where it is so modern a car characterset would be better don't you think? You'd see moving cars as well as parked ones.
Also as far was details go.... don't forget the shoulder white lines on the road. And your plants could use less saturation. They aren't really going with that tree you have from the RTP there just edit it out a bit and pick colors from those palets if you want to blend it in better. Trash cans and dumpsters would be good here as well... litter, parking meters, stop signs and lights... etc.
