I'm not happy with that RS2
If you are trying to tie what has become the commercial version of the RS2, the tails look short (should be full hook length), and it looks like you clipped the fibbets. The wing looks too far back to me (should be at about 25-30%) and it should slant backwards towards the bend. The body looks nicely tied. It's a nice fly. Keep tying and posting!
The original was actually tied with a very different set of materials. Beaver dubbing and hackle fluff. There is an interesting bit of history here.
