    Sounds like you did it just right.

    Next time though, I would not lift off the gas, and just shut it off with the key. Doesn't make much of a difference, but you might get some codes now.

    Let it sit overnight, then start it up tomorrow morning, and let it idle a bit to warm up... Then raise the rpms back up to 2000 and keep it there until all the smoke is gone. As long as you didn't raise the RPM above 2000, the likelyhood of hydrolocking is about 0.0000013%. And just to quell your fears, if it DID hydrolock, it would feel like someone crashed into you from in front. Well, and it'd sound like somebody hitting your engine with a 10lb sledge.
