Hard to really say from the picture orientation but it looks like the handle runs up the left hand lifeline and passes under the thumb pad, rather than nestles under the heel pad.
Also, the right forearm seems to be above the left, rather than under it.
All in all, the left hand appears to be strong whilst the right appears to be weak.
I'm going with Turned Left Hand on this one due to the position of the left forearm. It's not vertical. If the dude had on a watch you could see the watch face. Another good check is if your hand is vertical you should be able to see the WHOLE grip cap. If the Left Hand is Turned you will not be able to see all or any of the grip cap because your forearm will be blocking it from view.
What we really need to see here (in this Top Down view) is a Strong Single Action Grip with the Wrists in both Impact Fix and Adjusted Address conditions. Anybody?
