Here's some pointers. It looks as if you may have had a bit of tearing?, because it seems as if the scapular feathers are a bit too far back towards the tail. When a duck is in it's relaxed pose (sitting), it's wings are sitting under a layer of feathers also known as the wing pocket. If you can master this folding process of where the wings actually sit, then the bird really comes together alot better. Some people will cut a relief cut in this pocket, or a relief in the form itself, but it's not needed. You really don't even need to wire this area, or even pin it if you wrap the completed duck with plastic wrap. I like the fact that you put an "S" shape curve in your ducks neck, because they all have that bend in their neck, you just went a bit longer than needed. Next time save the neck and head (if you go with an artificial head), and use it's length as a reference when you actually are mounting your bird. If you pushed down on the head and sort of flattened out the neck against the "shoulders" of the duck, it would look a bit better. I know it's your second sitting bird, and they're a bit harder to make look anatomical than a flying bird, so for that, you're on your way. I said in the past, that I have replaced quite a few of my "first" mounts as i improved. Did you use any photographs as a reference guide to help aid you while you were taxiing? They are invaluable! So have them there the next time. I think the breast and feet look great, and everyone gets better each time!
