Today, I trimmed the Griffith's Gnat hackle a little bit to make the
hackle length is about 1.5 times hook gap. Here is the picture.

I have to say I do not have the genetic hackle to tie the fly. I use
the smallest Chinese rooster neck feather to tie the fly. And I also
reduce the wrap of peacock herl. The pattern looks a little weird. I
just want to know whether it looks better than my first one. Or there
is anything I should pay attention to when tying this pattern again.

Hello Da:

If you use Google Images to search for "Griffith's Gnat"
you will many photos that look a lot like your trimmed version.

But you can tell (just by looking at your photo) that you trimmed
the hackle before winding it. Trimmed hackles have thick,
square-ended fibers, rather than fibers that taper to a fine
point.
