Not dissing your soft hackle (the body of it looks great!) but it's one of my favorite flies, and I'd like to share a couple of tips I've learned after tying a gob of 'em.
1) Make your dubbing ball a little further back from the eye, and leave more room up front to palmer the hackle.
2) When palmering the hackle, leave a little gap between it and the dubbing ball, so when you whip the head, the hackle can be smoothed back a little and won't be as perpendicular to the hook shank as what is shown in your picture. You'll find the hackle will still pulse as it moves through the water, but it will sweep back more smoothly and look more like wings and legs when folded up against the pupa. The dubbing ball will keep the hackle from riding flat on the hook shank.
3) It's a preference thing, but I like a little less and smaller hackle, particularly for soft hackles used in trout fishing. I find myself somtimes pulling some of the hackle barbs off when fishing.
