I actually love the simplicity of this, I'm not big on the ramp bricks that're a part of GSF's bricks, I still enjoy this. Try using brighter colors on some of the buildings and add a little twist of your own. Being accurate is one thing, but making a build eye-candy and fun is to put your own twisr on it.
But I'd love to help, I love default and I could do a little work with my free time.
