First Teal

The biggest thing that I see is that you need to taxi the neck skin toward the head.
Look at a photo of a standing teal and you will notice that the upper part of the pinkish breast feathers (where they join the head feathers) is almost level with the top of the back.

maybe next time you wrap a body, build in the clavicle area, so you can tuck the neck in more to the body.

 

I don't think your body's too big, in fact it may be a tad too small. Head seems really big for the body. Follow Nancy's advise, and try to taxi the skin forward of the shoulders toward the head as well, might smooth out the wings a little. What you've seen is wings tucked into wing pockets, the long feathers on the side of the bird. Next duck you do, practice tucking the wings with a clean ready to mount skin, you'll see how they fit.

 

Your wings look to low on the body. Did you leave the humorous attached, wire the wings? Either of those or both can make it hard to get your wings folded and up where they go., at least I struggle with it. That's one nice little green winger. Hope you are going to Mexico for ducks?

 

Looks much better

 

Wow. Works for me. Well done.

 

Love the balance, and angle of eye...something cool about it...

 

Looks really good!

 

Try moving your wings back just a wee bit. You will be surprised what it might do for you. Drop the bird in the freezer before you leave and rework it after you get back. Bag it good so it doesn't dry out on you. Have fun in the sun.

 

I don't think your wing position is off by much, if at all. I think you should cut yourself some slack when it comes to getting the side pocket feathers to cover the wings. You simply can't make it happen if the feathers aren't there, and that's the situation you have with that bird. It isn't fully feathered out yet. It was close, but it wasn't quite there yet.
You can tell by looking at the scapulars and, to a lesser extent, the under tail coverts. A fully plumed GW teal will have no brown "summer" feathers anywhere, and there will be a thin black teardrop shape in the scapulars. It's almost literally the last thing that they grow when they are moulting, so it's the first thing I look for if I'm trying to evaluate a potential specimen.
They moult later than most ducks - sometimes not until February - and it can be very hard to get a perfectly mature specimen.
The body (breast) should be a little deeper right in front of the legs but otherwise that's a pretty good effort for a pinfeathery teal.
