Your pictures inspired me to tie up some Ray's flies this morning. Thanks.
As for the red gill - I like it. For those who are speed tying consider using a white or a pale yellow thread to tie the tapered head on your fly and then use a fine tip, red magic marker for a red gill effect. If I am going to use white or yellow thread I also put a black stripe on the top of the head. This makes the peacock herl look like it continues to the eye of the hook.
Using markers is an obvious way to add the red gill and I like it because it is quick.
