I've done a little more tweaking. Fixed the end of the scoreboard and added a few of the signs. The park is going to be similar to Ebbets Field - signs all over the OF fences. Since it's near an industrial area, I added a background. Just to see how it'd look.
I'm happy with how it's looking so far. The textures need improvement - the fence for example. But that'll be my last step after I get everything "built".
