This is a great subject. I think you could make it look more like the rubber stamp that it is by choosing a different angle...more dramatic. The red shape gets lost amid the trees and buildings.
Thanks,Milo. I have another that's quite a bit closer and a somewhat different angle and I'm still undecided about which I like best. I like the feeling of coming upon this thing in the context of the surrounding park. It certainly wouldn't work at all in b&w because it would blend in too much but the red stands out. Maybe I'll post the other as well.
