Composing with Triads Sharing a Tone

This is a simple composing exercise I did. I composed 4 bars of music using only major and minor triads. Each triad had to contain at least one note in common with its previous triad. What is interesting is that I composed this without even listening to the music / notes as I wrote it. I trusted the method. I think it works. Judge for yourself. I doubled up on some notes of each triad for orchestration purposes.
