I've found that the very best way to make sure you get replies is to continue to work on it even after you post it. Don't sit back and expect everyone to find all the little flaws. Take a 10 minute breather, flip the image horizontally, and look for problems yourself, then spend a few more hours on it and post an update. It's an acceptable way to bump it and it improves your ability to look at your own work objectively.
I'd been working on it for over a week and had been constantly updating even after the original post. I shouldn't have to bump my own post to make other people see it. Thats ridiculously illogical.
As for the 'water that is going to flood the park', here's a link to a placement test of the park:
http://thegriddle.net/isocity/jig_park.htmlThe turquoise is going to be transparent and I anticipate changing the entrance to the parking lot a bit, finishing the roller coaster, adding scenary and stalls for games or food, finishing the carousel, and adding a shipwreck in the top left corner and beachgoers on the top right.
