Hey there,
I like how your movements are lyrical (your moving/reacting) to to the words of the music. I also like the attitude you supply with the song to, it's very enkeeping to the theme
My first oppinion is that you need a bigger space. It'll help as you won't have to worry about hitting any objects. Also distance your camera so we see your whole body. As when you dance you dance with your whole body
.
The only other thing you need is confidence which I think will come with more space. Basically be less self aware in a shy front and more in using your body.
I enjoyed it. I strongly ask you to try a bigger space though so you can really use your body in stretches and movements.
*giggles I did gangnam style in a mascot suit once* was really hard as the feet were wide and heavy.
Oooo can you do body ripples or side ripples? That would look really awesome with your dance too ^^
