This animation is done for it's sole purpose to be a decent loop animation. This is NOT rotoscoped. I literally did this with just careful and consistant frame-by-frame drawing sequences and no, I didn't use any references either. The quality looks nothing like this when I rendered it. I think its this site that screwed up the quality, so don't come crying to me about it.
I grew up listening to Miami Bass/Booty Bass music and I think it's hands down the best music genre to dance to as far as being out in clubs, etc. The epic booty music is cut to shorten the video loop, so enjoy these three badass sistas, mang.
