The picks look like they are shaped well. Especially the bristle and the wiper insert. Oddly enough the hacksaw blade hook looks nearly identical to the first pick I ever made, and like mine you'll probably find it needs to be thinned out a tiny bit more and definately made into a short hook instead of the full sized hook, or not. Such is the nature of homemade tools paired with individual preference.
I see someone glanced at my how to after all.

You even cut the grooves well and got the recoiling fairly tight, but I can see you either need another pair of lever locking pliers, or just a longer spring. A fairly unusual thing to see in a first set. This, the snap gun, the decent assortment of picks, that's an A+ for effort alone in my book.
