William, I could have just flocked them grey and brown and they would hunt just fine, but where would the fun be in that. One thing that I always teach is "do the best you can in everything you do, not the least you can get away with". The trouble with most ducks is if you have 42 photo references of some species, you will have 42 different looks to them. I pick out a pose or or color layout that I like and start carving and painting till I get as close as I can. Painting anything, especially detail over flocking is a challenge as you already know, but there is no other way to do it and I won't hunt decoys that aren't flocked.
