I don't really compliment people on their homemade sets (other than raimundo

) but that's the best first set I've ever seen.
My only gripe is that the handles aren't also sanded, but that's just a personal thing. The important parts of the picks are incredibly well done. The dimensions on the picks that I use most, the hook and half diamond, are perfect. The spacing on the first sawtooth rake seems a bit small, but whatever works.
I'd suggest making a Peterson gem style pick. Basically, make a hook about the size of the one with the blue handle, but instead of making the tip flat or rounded, make it pointy.
Link to Peterson's pick.
As for tension wrenches, I'd suggest making some similar to the ones HPC produces.

The first is just a tension wrench, with both blades of the same thickness, but of different lengths. The longer one allows for tension at the bottom of the keyway, while the shorter end allows you to put tension at the top of the keyway from the side.
The second one has two blades of the same thickness, but of different lengths also. Again, the longer blade for the bottom of the keyway, and the shorter blade, twisted 90 degrees, which allows you to put tension at the top, straight up. This one is often easier to use without having the tension wrench slip out, than the shorter blade on the first tension wrench.
