Very nice job. I bought a dozen Herters Model 72 Mallards when I was 14. They cost $28 for the dozen - which was exactly my weekly takehome pay working as a stock boy after school and Saturdays. I still shoot over them.
Your paint looks great, but I do have a couple of suggestions. Here's a pic of one of my wooden gunners. I think the important thing in painting gunners is to give the birds the visual cues they look for.

1) The same light grey you use on the sides also goes on the "back", left and right, with dark down the center. The back is really the feather groups that hang off a bird's "shoulder" - the scapulars and tertials and their coverts. Around the edges, use a dry brush to soften the transition to the dark color. These grey patches give a mallard their characteristic look from above - something I never appreciated until counting birds from an airplane.
2) Note the white between the grey side feathers and the black rump feathers. It is an important field mark, too. Again, best if softened between the grey and the white.
3) Head seems to shine a lot. Not a big problem but better to dull it down. Are you painting with latex house paint? That's what I use for gunners. I get Home Depot to mix up an 8 oz sample - about $4. Some places, like local hardware stores, might even have smaller samples - useful for things like head and bill colors. Either way, get it in dead flat.
4) Not important, but, drake Mallards rarely show the blue speculum when at rest, the hens show it more frequently.
I hope this is helpful. If I have time later today, I'll snap some pics of my Herters Mallards, drake and hen, in their gunning paint.
Keep up the good work - I look forward to seeing the "after" pics of the whole flock.ll the best,
