I have to say, ok. I've honestly never been a fan of Tae Kwon Do, but that aside, I would say you are getting there. Your form needs a little clean up, could be a tad bit tighter. Watch your angles, Where it's supposed to be parrallel with the ground, 45 degrees or 90 degrees. Also, I wouldn't despise the basics, something that may help it flow a little better, feel a bit more natural is adding some basics inbetween all the flips and spins. This is just my opinion, one thing I learned in Japan, and the difference between American style martial arts and over there, is attention to the minutest of details. Every move has to have purpose, has to be deliberate and exact. Spins are nice, flips are nice, but they take time in between each. Plus, putting the basics inbetween will give you a chance to catch your breath inbetween and make it look more effortless then tiring on you.
