Nice tie. I fish damsels a lot esp in slow water as John said. One tip I was given that you may want to consider is a dubbing loop/brush of antron for the body or (the ultimate) a dubbing loop of clipped marabou. It takes a while to master keeping the fibers in the loop but man does it look good underwater when it's slicked down. I think damsels have their gills on the side where the legs are tied in and the natural breathing action of the marabou is too much for the fish to resist.
A killer pattern in sections of the Nissitissit and Squanacook rivers here in Eastern MA.
