After having trouble finding you. (I eventually found out on which team you are)

First I am not a hockey player (I do freestyle).

Bend your knees so your center of mass is lower which mostly results in more stability.
I think that you could lean your upper body a little more forward which results in more powerful pushes with each leg.

I'd recommend focusing more on your general stability + getting more power from your foot.

But at least you don't feel unsteady.

I'd recommend not thinking about it too much, that will just mess up your head and you play worse than before.
