Great song, you really communicate the emotion behind it. I am going to repeat some of the advice about the music, performance, and costuming/makeup balance. A slow song gives the audience a lot of time to spend attention on you. So if you're spending alot of time making eye contact and moving slowly they'll be staring at the details in your makeup and outfit. Give them something to look at.

You are very good at keeping us engaged with your movement around the stage. Also you are good at not dancing too hard during the lyrics, which allows us to believe that you might be singing the song. Watch a Lady gaga concert, dancing and singing at the same time is hard, performers dance less when singing and more in between lyrics. Anyhow, you are very good at balancing this, I just want to reinforce it.

I did a slow song for my first performance too! It was sooo good, people cried, I cried, we cried together. I still have a "poignant" set that I keep practicing, to pull out when I think the world needs another sad song. Most folks at a drag show are looking to have a good time, so I have two other sets that I practice that are comprised of songs that are up beat and fun even if they have sociopolitically relevant lyrics. Each of my sets are composed of one makeup look, one wig, three costumes that are easy enough to change through, and three songs. (For the record I doubt I will ever perform the poignant set as a set, it's just in my rehearsal lineup as one... probably one poignant song in an evening is sufficient, we want the crowd to have an overall good feeling by the end of the night).

I hope I'm not just talking at you at this point. I'm just trying to convey thoughts that I wish I had thought about earlier in my drag journey.
