You have received some good info from some great experienced tiers, some of who guided me along a few years ago when I first started here. They are all correct about tying improving by learning each skill and practicing it. As you progress you will see the improvement in your own work. Some will say to use YouTube...that is ok but you have to be careful. Anyone can post a fly tying video whether they know what the hell they are talking about or not. As you tie more you will be able to tell the true artisans and the bull crappers. Until you get to that point, keep tying, keep posting ,and do not be afraid to ask for help or opinions.....everyone has one of those...lol. As for your flies, you have done extremely well for your first ties. Hans Weilenmann has a great you tube page and a website with some of the best tiers displaying their flies. Daley MacPhail is another great you tube teacher with hundreds of tying vids of the very best quality.
