look at your apendages, they were pretty much just extended alot.it was relaxed in the beggining. it was sloppy also because your body was rubbing against uke alot. again i say about a 4.5 or 5 beacause of those variables. next time dont forget to relax mid-attack and to add speed and style. its good uve got destruction, but it lacked flow too.
keep it up and always learn from comments.
