Roller Coaster, Carnival and; Amore builds - please post your pics

I possibly will eventually put mine up on the exchange. It is just my first attempt at making a roller coaster and want to see how far I can push it and what works and what doesn't at this stage. I've just been getting Sims to ride and the roller coasters work. I now need to look at what needs changing with the rest of the lot.

EDIT: Much later: It's up. Exchange link is: http://www.thesims3.com/assetDetail.html?assetId=7860207
