Hope This Info Helps
All of us who tie believe our flies are a work in progress. You show obvious talent and ability as a tyer.
My suggestion on body proportions is a simple solution. A small ruler and extra fine point Sharpie. Then mark the the underbody with the head size, the location of the body segments and when needed allow for the ostrich herl wraps (approx 3/32" or 2 mm) between the segments. Be sure to allow for the throat wraps as well. Start the tip/tag area directly above the barb of the hook and the rest will fall into place.
I'm not trying to steal any fire from your post...but I've attached a couple of photos that illustrate what I mean about marking the underbody.
