Nice work, ry1220. Nice to have more stadium creators join in.
I can see I'm modeling a lot more detail than you - a lot more than is really needed. But I enjoy it (when it works - don't enjoy working on something for an hour and thinking it looks great...and then looking from another angle and seeing that it's screwed up with no way to fix it). I redo a lot. I'm not much of any artist but I am persistent.
And if you guys want to see an awesome model, go here
Yankee Stadium 3D Model . He's modeled 1960s era Yankee Stadium including the complete exterior. It's amazing.
