Nice fly (wire body?). I'd shorten up the tail a little bit.

If you're interested, Tightlines Productions has a good little video on a little black stonefly pattern
Really good looking flies! I tend to fish simpler, suggestive patterns and the fish don't mind. For strictly fishing flies, I replace the biots with rubber. Easier and more action. The biots look way better thogh!
