Help with Suburban layout

[Dreamcat]

I'm trying to make something a bit more realalstic than my 100% grid cities, and here's what I came up with.  However I'm not all that happy with it, and I need some help.  If you could tell me places which need fixing up, or just overall crappy.  Also I need some help to decide which trees to place.  I was maybe thinking about starting over, but I just need some tips on how to improve.  I've got the general layout down I think, I just think it's the neighborhoods that get me down.

It's not bad but I'd suggest you downloading custom houses and trees. Also take a look here. These "show us" topics are the perfect place if you need some inspiration.
Good luck!
