Uck. My ukemi isn't great at all. I was considered to have great ukemi in my old style, but in the world of aikido, my ukemi is.... sufficient enough to prevent injury, but I still need plenty of work. I do take it as a compliment though when sensei or another sempai uses me as their uke for demonstrating a technique. Especially when they purposely turn my fall into a breakfall instead.
I have to agree with others that those who have great ukemi are not afraid to take a fall and they actively work on it and try to improve. Anywho.. that is the opinion of the high and mighty 6th kyu with 3 1/2 months of aikido experience. LOL!
