Am I Doing This Right?

Hello,

    I picked up a banjo a couple of weeks ago, and I am starting to get serious about practicing with it. My previous musical experience has been as a drummer for 14 years, and because of it, have a slight case of carpal tunnel. I understand the importance of technique and tension free playing, so I trying to master the hand movement before I move on to anything else. When I do the basic clawhammer stroke, my wrist twists slightly toward the banjo head, and I am just wondering if this will be an impediment to my progress later on.
