I want you to improve your flies. With that in mind, here is my critique. You lfy is on top and a typcial fly I pulled from Google Images on the bottom.
I think the hopper pattern below is tied on too short a hook. A hopper should be tied on a 3X long hook.
I also think the body takes up too much of the hook gap. I think fish will hit the fly but you will have a hard time hooking up.
It is hard to tell if I am correct and a side view of the pattern out of the vise would be better.
Compare your fly on top with the foam hopper below and compare the hook length, postion of the hook relative to the fly body, and the hooking gap.
The pheasant tail pattern below should NOT have the tail fibers cut to length. They should be tied to the correct length so the fibers maintain a taper. The tail should be as long as the body so measure the fibers for the correct length againtst the hook shank and then tie them down. Then the tail to body proportion will be correct and the tail fibers will taper.
It is hard to tell about the bead but it looks too big to me, and takes up too much of the hook shank. I think the bead throws the proportion off, especially with the hook you used (see hook criticism).
I suggest you tie a PT without the bead first then add the bead after you can tie the fly better. Once you learn to tie a properly proportioned PT, you will have a better idea of what size bead to use.
A lot of the above problesms are that you again used the wrong hook. I think the hook shank is too short to fit all that material on along with a bead and get a proper looking PT. A PT should be tied on a 2XL nymph hook.
I think the zebras are the best, I think the bead size is correct. I do think you tied the fly a bit too far around the hook bend. You tied down the curve to the middle of the hook gap.
The body should be thinner or maybe it is the shadow that makes the body look too thick.
You HAVE to tie flies on the right hook. The hook is the skeleton of the fly. It is the form that determines the shape of the fly.
Try to get better lighting for you next fly photos - no side lighting and no shadows. Try my styrofoam cup fly photo method.
