Armor looks pretty good I think. I'm not so sure how the head's positioned because it's viewed side-on while the neck right below it is still bent, if you get what I mean.
As for the shoulders at the moment they look kinda wonky, like one's higher than the other. The middle bits of the chest scales don't look aligned properly either, like they're too far over on one side.
As for the wing shoulders, they should start right "above" the shoulder, if you get what I mean. Like in this.
Looks like a great start though.
