Wing depth is pretty much spot on, maybe one strand less, that's all. Lose any more and you're left with a skelf of a wing which no use for a sedge pattern, unless of course, you
want it to look like that.
Also, considering it's a sedge, try the trailing edge pointing down like this... / rather than up like this ... \ you'll get a much more realistic looking wing shape.
One more thing, it might help if you tie on each wing separately as you would on a spey pattern. It doesn't always make a great difference but I find it can help with deep HP secondary tented wings.
Oh yeah, shorten the wing slightly and you're right, ditch the tail.
