Very cool !!!! I really like the color combo and the proportions are good as well. I would fish this through any boulder garden any place, besides that just gives you the excuse to tie some more. About the wing thing, I am by no means a pro at setting hackle tip wings but can give a few pointers. When you select the hackles you like for the wing be it four or six hackles and you go to strip them to the desired length the bottom of your wing will need to be stripped back just a bit more. this will aid in the wing setting lower to the body. also always remember to flatten the stems before tie in. to get the correct curvature to the wing use your thumb nail and index finger to curve the stem to your likeing. This last bit takes some practice but is well worth the effort.... Nice fly!
