Thanks for the comments.

Beautiful! What color did you use to highlight the black?
The black was based on Foundry Black (34A) then adding Slate Grey (32A) in a couple of layers and a few highlights with pure Slate Grey (34A). I have been experimenting a bit with predominantly black miniatures lately for a couple of future projects. I'm finding it difficult to get consistent a finish, but found that ambient lighting conditions can make quite a difference painting lots of black.
the dog food can is a priceless detail!
Now what about the dog and the car?
I wanted to do something more than a plain base for him. The small piece of twig seemed right, but the empty can of Dinki-Di came to me in a flash of inspiration. I made it by drilling out a piece of plastic rod and adding a small disk of plastic card for the open lid. I tried printing out a label, but the resolution at such a small size was awful, so I hand-painted it.
No immediate plans for the car or dog yet, but would like to at some point.
