looking good...lots of adrenalin ......RELAX and enjoy the trip.
the wing (nice job) isn't the only part. Let's just think, you spoke about not being happy with the tail and topping which means you're on your way into the world of "what is good"? That is a long, difficult and rewarding quest.
You have color, textures and in the case of crests glossiness that are very different from bird to bird and if the birds were healthy or not.
body hackles, collar materials etc. barb length, thickness, fluffiness, taper, coloration, and in the case of guinea or teal, the type and size of the patterning.
The only way to understand it all ( nobody can) is to play. trying different styles, etc will cone along.
to appreciate the subtle qualities of tying I suggest you use cheapo bare hooks and try different maneuvers.
examples.... just make body hackles experimenting with tapers and shaft stiffnesses. how many turns of hackle will it take to make 4, or 5 or 6 etc turns then get a nice length of
fibers in the throat area.
crests...come in many lengths. chasing the correct length for a fly is time consuming at first. try finding a crest for the topping that is exactly the length of the wing ...try not to cut them to length. for tails, it's almost the same thinking. again practice practice..etc
throats/collars. what length fibers? these feathers (like guinea) have short, heavy shafts some with longer more flexible shafts (rachis). they all have sweet spots to look for.
dubbing...what is sparse? heavy?
tinse....widths and thicknesses
silk....do you use 4 strand? 1 strand?
head size...this is arguably the most important factor when tying flies. how many wraps are needed yo hold stuff in place? waxed? not waxed? size? 18/0 diameter threads versus 6/0...what the hell is a denier!!!!!!
WHAT IS CORRECT !!! Your idea of correct/wrong is entirely up to you. you can consider this "style".
