Leaping Deinonychus Up Close, He's Not a Duck!!!

     Again, when people from school saw one of my sketches of a Deinonychus, they were certain it was some kind of 'Prehistoric Duck' (and they do not look like ducks to me!).  So, to make sure my prehistoric raptors look like modern raptor, I when on Google images and compared photos of water fowl with photos of eagles and other modern raptors.  Here's the result of that.  I hope the fella above does not look like a duck, but if he still does, tell me what I can do to make him look not like a duck, but as a predator while still having a good healthy coat.  Thank you!!!
