Welcome to this great forum community, @Kim Edgerton!!
Oftentimes, looking up is not a curiosity issue but is rather a result of something gone amiss earlier in the swing motion that caused the head to come up prematurely. For example, perhaps the hips stopped their lateral targetward move in the downswing and thereby allowed the rotational component took over, or the golfer's weight drifted back into the trail side, or a steep path caused the golfer to pull up in order to prevent the club from crashing into the ground, etc. Whatever the cause, it's best to try to reverse-engineer it through video as any advice to "keep your head down" is flawed as it does not get to the root of the problem
