Thanks for your comments everyone.
Hilbert, the bucket is from my parts box, I don't remember where it came from. The rusty muffler was made by first painting with tamiya red brown and then while the paint was still wet going over it lightly with MMP rust powder.
Martin, I may also do a Jagdpanther. I have one wainting on the shelf. It just depends on whether or not i get to it.
