The weave/crochet will come along with a little practice, will be a good idea to keep a record though of even the worst ones. I wish I did to see what I did and keep track of my progress.
I like most of them, really like the bottom one and third one. I have always liked palmered hackle tying and need to do more of it myself.
As far as critique, I agree that feather over palmer is a little much and a hackle collar would really make those feather pattern full without being too busy in one area. I think the tie off is too large and takes away from some of them but that is just my preference. Might be a good fish catcher that way. The top picture, the one with the side winds looks good but don't worry about tying chenille over it. It will look better once you get them tied in right at the head. It takes a little finesse to get it right but strip a little of the feather that is gonna be tied in and try to match them as far as the same bend and side of feather that is up. Getting them matched up will help with a proper fall and not a whirl wind action that might give it an unnatural action.
I love taking my kids fishing, now if I could just manage to fish at the same time.
