Look Great to me.
Only things I (personally) would change would be this:
the abdomen may be a tad short.
I would make the first wing case a bit thinner.( i taper mine to get larger as they go forward, PERSONAL PREFERENCE.)
i would add one more section of natural skin to have 3 wing cases total (PERSONAL PREFERENCE).
I think you may want to re- position the legs. To have at one set face forward. The legs are a tad un even not that it would matter to the trout. Always cut them longer than what you think. You can always take off material but can add it once its gon
These are just things that reflect on my style, and things that i have had success with.
Main point is that fly will catch fish, hands down. Looks to be a great anchor fly as well. I would definetly tie that on the end of my rod. It doesn't matter really what anyone on her says it will be the trout that decide in the end.
GREAT FIRST CRACK AT STONES!!!
