In my personal opinion it uses very little battery power, so unless you have the screen lit on all day long you shouldn't notice any change in battery life.
This theme is very pretty. The icon set is nice, and the animation is smooth. The only thing I would mention is that when the application menu is open, the name of the icon you are hovering over appears as white over the white snow. Only the edges of the letters are visible when they extend into the blue sky background. But that is a minor nitpick. Beautiful theme!
