Like all of your birds, I think the Sleeper looks fine. On your Question 3 - do you mean tertials and primaries - instead of secondaries and scapulars? I see no big problem but I would:
Primaries: You have them stacked correctly (too many guys nest them concentrically) but I might broaden the tips a bit so the inner web comes off the main rib (rachis) at a larger angle. The key thing is that the inner edges align and the outer edges show separately, usually about 1/8" parallel to each other. And, because the outermost primary is shorter than the next, it is the
second primary that you see on top. (Technically, primaries are numbered from the inner wing out - so I am referring to Primaries 10 and 9 respectively.) On this Wigeon, notice how the tip of Primary 10 disappears beneath Primary 9.
Tertials: Again, they look fine. They do not really droop in divers like they do in many drake puddlers (Pintail, Wigeon, Teals) so I would leave them as they are.
Regarding texturing. Lots of ducks have been shot over smooth-finished decoys. But, I really like the epoxy+sawdust method I started using last year - I just cannot be sure of its long-term durability. I did these Herters Model 72 Cans last winter and did my 40 Broadbill this year. The paint is dead flat because of the rough surface. I will probably do this to my E. Allen birds (Mallards and Blacks), too, when they need new paint.
Finally, like Pat, I would paint the eyes. Glass eyes are lots of work and give water an opportunity to get under the skin.
I hope this is helpful - and I look forward to seeing your finished birds.
All the best,
