My (woefully inadequate) effort to imitate Bach

I tried to compose a two-part invention a la Bach just for the fun of it. I quite like it, although it is far from as perfect as Bach himself would have been. For those out here who actually know the rules of counterpoint, I don't, I guessed and used my ears and my little four-part harmony knowledge. It probably contains lots of errors. I know that, but I can't correct that immediately I might revisit it some time in the future, but for now I like it.
