Lens disortion in front pics

[lmo1]

In the first image, my midface ratio was approximately 1:1, while in the second pic it was somehow 0.95:1. Also in the first pic the canthal tilt looks slightly negative, while in the second pic more neutral. Why does these happen, lightning, angles or smth else and which is my accurate ct and midface ratio in this case?

angles for sure regarding canthal tilt you also look more tired overall in the first pic and eyelids are barely more droopy. Face probably looks narrower due to distortion, and midface looks compact in first photo
