They are looking good, and I think you may have passed the point where this advice applies. For anyone who wants to learn how to do the shuttle weave my advice is do them in half dozens. There are really three stages to tying these - foundation (underbody, bead etc), weave, and finish (thorax, legs, hackles etc). If you tie up one fly, you learn things on the weave. Then you finish the fly, and prep the next one. That takes just long enough to forget what you learned on the weave. If you prep 6 to the point that they are ready to weave. You can weave all 6 one after another, taking only the time needed to secure the woven threads between them. This shortens the learning time drastically.
