Pretty sure that's Ten, if the garb, hairstyle and manner are any guide. Besides, a ferret really seems to fit David Tennant's bouncing-off-the-walls hyperactivity.
Believe it or not you guess it absolutely right. I really liked Tennant's portrayal and since this was done for another fan I'm happy to see that I was right in choosing ferret to represent him. ^.^
