Great work! Unfortunately I'm don't feel qualified to review crypto
primitives for correctness - this is why we went with reference
implementations for curve25519/ed25519. You should see about getting
your implementation into NaCl or libsodium.

We should see about making it possible to use libsodium for some
crypto...
