Not really doing the pattern much justice here but you can see the basic tying method.....
Hook - Shrimp hook to suit. This is a Jardine Gold #10
Thread - Dyneema/GSP
Legs - Should be a covert feather but i've used a light brown grizzle. The one in your pic looks like partridge.
Body - VN Nymphskin
Tying process....
Wind on your dyneema to a point opposite the barb. Strip one half of the feather fibers away and catch in 3mm of bare feather stalk winding round the shank. Wind the thread back up to the point opposite the barb.
Take a few inches of the nymphskin and cut the end square. Catch this in by the corner and wind the thread down over the skin to where the feathers are protruding. Half hitch the thread and leave to the side.
Catch in another bobbin with dyneema at the eye. Cut a piece of self-adhesive foil the same width as the hook shank. Catch this in working down towards the bend stopping opposite the barb again. Tight wraps of the thread will cut through the lead. Add further layers on top of the previous to build up a hump shape. Try to end up with the bump opposite the barb (mine is a little too far forwards). Give the whole thing a coat of superglue.
Paint the body white - this will help with the transleuscency. Coat this with a liberal amount of Sally Hansen Mega Shine to build up that shrimpy shape.
Wind the nymphskin up towards the eye creating the segmented effect. Catch in the nymphskin and whip finish. Trim the thread. (unlike me, you should let the white paint dry first!

)
Remember the other bobbin from earlier on?? Colour 4 or 5" with a Pantone marker. Begin to wind the thread back up the body following the segments. On the second turn, bring the feather forward under the fly catching in with each turn towards the eye - be care ful not to trap too many fibres. Trim the feather and give your shrimp a nice paint-job.
To finish, give the body several coats of Mega Shine. Done.
