nothing much i would do here, actually, maybe a little bit of space at the top - which could be solved with lower perspective. that also has the added benefit of bringing the skiers closer to the "horizon" here, thereby allowing for a similar crop to keep the position of the skiers while having more space at the top.
am i being too convoluted here?
if you have the time and it is your sort of thing, you can consider cloning all the other little figures in the distance out.
a pretty nice moment, though i wish they were more evenly spaced out - but that's not really within your control.
do you have other shots with a nicer spacing? the gap between the 4th and the 5th here is the problem for me.
