Very nice fly! Found a pattern called a rabbit matuka that is close to that and i have tied a few now but yet to test them. Here is the page i found with some interesting color combos - Tip Dyed Rabbit Strips.
I take it you are using squirrel strips... is that what you used around the collar as well?
yes, also the body is a new material we all overlook- felt! if you pinch down on it and pull fibers come out as perfect dubbing! it is really easy to dub to
