alright so i thoroughly enjoyed her performances (well, what i got to see from youtube) but i do have a few pointers.
1- get her off HEELS!! all of her previous performances kicked ass and this was mostly because she was wearing flat soled footwear, she looks off balance most of the time and isnt dancing nearly as well as she did in her rehearsals. sure it makes her ass look fab but you cant sacrifice those britney moves, one of the only reasons im still a big supporter ESPECIALLY since she lipsynchs every single song
2- get her to do more shout outs it'll make the performance all that much more personal
3- more belly-baring tops, pants.. basically britney circa 1999 with style

keep it up!! you're doing great
