lookin good, you seem to have improved a little since your last vid. your hits seem more controlled now and less jerky. You were more on beat in your last video, which i really liked, but it's good to see you're actually dancing to the music and enjoying it.
I'd like to see more head and neck movement, you seem a little stiff. Your waves looks good, but could be a little more fluid. Also work on the isolation, lots of times random parts of your body are moving by accident. It's cool though most of the time it's just your hips involuntarily grooving to the music
Oh i'll be brutally honest. Your locking sucks. I'm sorry.
Don't be discouraged though, download more clips and keep practicing at it. Remember locking is always on the beat. so keep that 4 count in your head.
