Awww, it's cute side about Maki and Santa. I love it~~~
But... Eli and Santa??? You mean Дед Мороз? Hm? In Russia New Year is more celebrated than X'mas. /Hmmm.../
Anywhere, it's cute story, so I will not bother about details.
@DnW7 doing some measuring in PS, her lower leg is only slightly longer than her thigh, which is close normal body proportion. It's not an uncommon thing in "heroic proportions" which are used in pretty much all comic styles in the world.
