Hi Baz, great effort mate thats a nice looking snatcher

and will defo catch fish

.
Only things I can say which may help or may not I don't know but anyway: perhaps the rib would be better with wire rather than tinsel? The jungle cock cheeks could be tied a bit further in ie a wee bit less of the black part of the JC showing - splits would be fine for snatchers too mate and save your better feathers for other flies.
Not critisizing just trying to give my opinion which may help?
Great fly though mate, could be worth knocking some up in 12s and 14s as well - that looks like a 10?
