yes you're still off balance.
take a look at your images #3 and #4. Can you shadow swing and hold that position for 5 seconds? I'd say no. You'd fall over because you're off balance.
Look at the roddick and djoko images i posted. You can shadow swing and hold those positions all day.
If you're balanced you get more power, more body into the ball, more control, easier to recover, more consistency, don't have to swing as hard, less stress on the body, takes less energy and looks cooler.
