Those look good to me and sure they will put a few fish on your line.
".....suggestions welcome......."
I personally tend to have two issues when working with the large cactus or estaz chenilles - more with how i want them to look probably than what the fish care - but both are about the profile/shape the chenille creates.
- Trying to keep the body full all the way up to the head is one. The cactus/estaz has long fibers but is not a dense chenille, so sometime the fibers get easily trapped down when you go to tie off and then it leaves a gap between the body and head, similar to your 2nd picture. To try and avoid it, you can add an extra wrap of chenille at the head to make it a little fuller, keep brushing back the chenille fibers as you lock it down to trim it off and then do as few hitch/whip knot wraps as you can get away with but have it still stay solid. If you get it right, the chenille hides all of the thread and leaves no gap.
- My other issue is at the opposite end. I like to keep the shape tapered down to the tail material so pretty often will trim the chenille at the back to get the shape right.
Again - both of these are cosmetic things to MY eyes and how i THINK they should look. Fish eat hotdogs and cigarette butts sometimes, so thinking us jig tyers would be a tad bit eccentric to them.
