I think this is a great picture of Jacque Kallis at the point of delivery.Key points to note:

-Weight is forward without over commiting-this allows him to get forward whilst being able to push off his front foot to get back equally well.
-perfect head position with eyes level
-feet not to wide
-shoulders relaxed
-knees slightly flexed
-his front foot shifts open which allows him to play straighter and through the on side more easily
-notice the way he has picked his bat up allowing for the "six" shape-very important to get this shape right
-bat face slightly open with toe pointing to first slip

Get this balanced set-up right with correctly picking the bat up and you will be a VERY good player!
