One thing about what you are fishing with is that you have to have faith in it, or you will not fish it properly or thoroughly. The other thing is that what you might call poorly tied flies are rough and actually provide more movement in the water than some well tied patterns. For example a Tom Thumb seems to get more productive as it is pulled apart by fish taking it.
Most flies are tied to appeal to aesthetics first and the fish second, so it really doesn't matter what your skill level is as a tyer, you can and will still catch fish.
Weedy what is that pattern? Could you show a pic from another angle?
