"Nutters" are good targets points like Ifrit617 said. You might also want to try commercial field points. They are not necessarily primitive but they work well. I use them and I imagine most primitive archers (at least in the U.S.) use them as well. Your two "hen" feathers look like they are positioned at 180 degrees. Try moving them a little bit to the right, referrencing the photo viewed from the nock end of the arrow. Study other people's arrows as to proper fletching placement. As far as tying on fletchings I tie on the back "tag" end of the "cock" feather with an 8" piece of art. sinew, thread, etc... using a simple running knot. I insure that I use only the first 1/3 (or so) of the binding material for this first tie. The extra binding material is used to tie on the remaining "hen" feathers. Thus secured I can position the feathers where I want with one hand without fear of them falling off. At this point I can either completely wrap all three back "tags". Then I tie the front "tags" of the fletchings, ensure that I have them positioned properly, then wrap them. You can spiral wrap the entire lengh of the fletchings if you desire, add several individual "ties" within the lengh of the fletchings, or add no binding at all within the lengh of the fletchings. Good luck.
