Here my CnC:
It's smooth, but it's wobbly, the jump doesn't have enough anticipatiom, but the run has too much, the jump is strange and the steps are too near, anyway, it's a good "first attempt with pivot", also, remember, pratice make everyone better and nobody is perfect.
My tips:
-Use a guideline (a.k.a. simply background made with a line) next time, so your stick will not move around a totally blank background.
-Remove some useless frames (or make the FPS higher)
-study someone else's (maybe a pro animator that uses lines or pivot) anims
-pratice, don't be discouraged if your first attempts aren't what you wanted, everyone was (or is still) a noob/newbie
