Fist of The Five Ancestors

Does anyone know this kata pretty good? I'm having trouble making these katas smooth and most times i feel uncomfortable in my stances. ex(cat,back and one point) My sensei says that stances look fine but i just feel so uncomfortable any suggestions.

Hang in there. It sometimes takes a year or more to get comfortable in a stance. You mentioned the cat stance. I notice kyus below brown belt generally have bat cat stances because they're not comfy. And I like the crane stance, but it seems to take a while for most people to be able to get it.
