I really like this, especially the wrinkled effect aound the edges of the rust
patches - it makes it look like a chromed coating flaking off rather than a
rusty metal ball.
If I had one criticism, it would be that that rust 'swirls' follow the shape of
the patches, which I'm not sure is realistic. I might have tried to make the
rust texture more finely grained, and disconnected from the patch shapes.
