This is BY FAR my favorite stadium. I experimented with rounded seats in the corners, and made a river behind left field. There is somewhat of a green monster in left, but its black. The overall shape is taken from old tiger stadium, but the field is more like fenway park. One of my favorite features of this park is that it converts to a football field with ease. IMPORTANT it is not finished yet, hence the random seats and foul poles and trees lying around the stadium. I clone those (using the clone tool) and place them where I want.

How did you get the rounded seats? I can never get that
I start with the first row, (the first row is most important, so try to get it as perfect as it can be) and then I repeat it one row back, I just extend the sides. This stadium was the first one I made with the curvy seats feature, and as you see it wasn't perfected. If you look at my more recent stadiums I've got the hang of it. It's a good technique to experiment with. The main problem however, is that minifigures can't be seated and also be facing a 45 degree angle.
