torti,
Greetings. Nice looking rat.
Per your request regarding improvements to the model, I'd have to say that overall it looks quite good.
You should try to work on the snout, and feet. A reference photo might prove useful here.
The feet are currently too pointy. Something more spade-like with texture detail would be much better.
The pink cone of the snout seems too large, and the absence of nose detail is noticeable. Try to get that cone smaller, and add detail to the nose, and I think you'll have a winner!
I think it's a really fine model, and would make a great addition to FSCS' lineup of baddies. Keep up the good work.
Thanks,
Seth Black
