That'll work! Nice job. I also use different colored biots for tails and wings just to see what reaction I get from the fish.
Here's a little tip for tying the wings that I'll share with you that someone just showed me. Instead of tying them on already pointed backwards, then having to trim the butts, tie them pointed forward with about 3-4 wraps of thread, then fold them back, wrap 2-3 wraps to hold them down and finish the head. That way there are no butts showing to trim off, and it really reinforces the wings. Plus, there's no chance of cutting your thread if you trim with a razor blade like I do (I learned the hard way. LOL)
Great tie and keep up the good work.
