1st shot, I'd love to see the centre, more than the sides in focus. Otherwise it's strong.
Second shot I'd probably lower the frame to put their heads very near/on the top third but I wouldn't move them to the left or right. The frame of the window where it is, and the rock wall provide a nice frame and push your focus to the centre. I feel you'd lose that if you were to shift left or right. In any other situation, I'd say it's best to move them to one of the side thirds.
Nice job though
far better than any of my first images!
