Nice job on the wings. Quill slips can be a bear to mount. If I could make a small suggestion it would be to either use a shorter hook, or make your floss body a little bit longer. Classic wet flies are often tied on short shank hooks, and generally the floss body should extend to some where between the hook point and the barb. Don't get me wrong it is a nice fly, I'm just trying to add that little bit of detail that will make it a great fly.
