Nice one Steve
It's a style that fallen from favour I believe because it takes so much practice to handle the materials well and keep the tension even. You have done well.
Have you looked at the Tiemco R200 nymph hooks they would suit that tying beautifully giving you a slightly longer shank to work on? My only worry with yours is that butt of the abdomen might compromise a good hook hold and penetration. Mind you the Yorkshire Sedge pattern hooks would do equally as well.
You've inspired me I am going to have a crack at some weaving again ...... maybe with twisted marabou. We cannot all afford silk you posh git.
