Those are much better, as I'm sure you knew. You're still shooting pretty much exclusively wide open - so it can still be sharper. You've dramatically reduced the camera motion problem, although even at 1/1000th shots like these will be sharper on a tripod than hand-held.
The steps shot is probably about as sharp as you can get without some post processing.
