Looks good and it looks like it'll catch fish.
If I was going to critique it though I'd say i'd want to work on the ribbing to get it moreof an "evenly wrap" so that all of the spacing and angles were the same. This is the problem most guys have when you blow up flies much larger than their original size; All of the imperfections stand out like a sore thumb.
But, shit man the fish won't see that! I think it looks awesome!
