this is amazing...Lol. the movement is very fluent and da frame rate worked well. 24 to 30 wud be even better, not saying theres anything wrong wit this! but its amazing wat u did wit 12 frames. i can only imagine how more frames wud blow us away even more. Keep up da great work. PROPZ
It looks like either the last two frames are separated by an unequal amount of time or you put an odd repeat in. That or she's about to take off before it starts repeating.
Other than the sorta strained look caused by weird timing, it looks great. Then again, I shouldn't really say anything - my animation skills don't go very far past avatar slideshows.
