I went for Ceberae. Lovely design, excellent personality, and retained the dog features the best working within the topic.
Other entries were excellent pieces, but were animals other than dogs. You could say they "strayed" from the topic.
Ceberae, my only negative comments on your design is that it would probably have to have some proportions tweaked to be animated effectively. The shoulder and elbow on the forelegs jam together and would have to be pulled further apart in the model, and also the neck is so far back that it would not be able to bite effectively. Would need to be pulled forward.
That would be the only beef if I were given that concept to model for a game.
Small things, but very important.
Good work everyone!
