Welcome to DV!

There was nothing wrong with your attempt itself, though I would have started differently. Not to worry, different techniques work for different people.

Please keep in mind that most people don't have success on their first attempt, no matter what technique they use. Patience and persistence is required for success. Some take longer than others to have their first lucid dream, so it's impossible to say when you will have result.

My best advice for you right now is to start keeping a dream journal. It's possible the best tool towards lucidity, and surely for dream recall, which is important.

Good luck, and don't hesitate to ask if you have any questions!
