Looking forward to your stadiums.
You didn't ask for any suggestions, so ignore these suggestion, if you like...don't want to stifle your creativity.
But I do have some.
Suggestions:
make billboards readible...make it daytime...don't completely fill the stadium bleachers and stands (all games are not sellouts)...make the names generic, so we can name them anything we want in order to fit our leagues (a big signboard saying FAROO6 STADIUM means it will have to be called FAROO6 STADIUM)

...vary the fence configurations...don't make all of the playing fields the same...on the outfield fences put the distances from home plate to LF, LC, C, RC, RF large enough to see.
