This is unfortunately dangerous. It means that you can provide proof of your vote to others. That's no good; it makes buying votes or punishing workers/family members/whoever for voting the wrong way much easier. That said, there are some really interesting non-interactive zero-knowledge proofs for elections that accomplish what you're intending without this flaw. Their main downside is that, compared to tallying, they're complicated.
