Skull Theory guesses? No nub in these pics but nice clear skull shots ;)

The first group of 3 photos is the ones I want you guys to guess on! and the picture on it's own is my sons (quite obviously confirmed) boy skull shot lol. I think from the skull theory possibly a girl. Anyone else have any guesses? I find out in a month but curious to see what other people think! thanks!

Leaning :DS:, but its not easy to tell, It could well be a girl as the chin is a little more pointy than your sons, BUT my gut instinct when i saw the photos was boy x
