Yeah, hips way down in the start - bar over base of toes and arms vertical. Those high hips are sending you forward and killing your leg power.
Don't worry about receiving the bar high - it's not a heavy weight. You have to receive it wherever it is. What you can do, however, is smooth out that transition; that is, wherever you receive it, be prepared to ride it down into the bottom rather than putting the brakes on for a moment and then continuing down. All snatches will be received above rock bottom, so you need to get used to a) meeting the bar where you need to and b) not hesitating when you receive.
