Just some size comparisons between these guys, I have approximent heights for them, nothing is exact. Mira is about my height.

Also Lady Mars is character I made for Nox and Mira's world and is loosly based on Steven Universe fusions. I just haven't drawn her on here yet along with her little group (except Asim and his daughter)
Her name may be Mars, but she is peacefully woman who just wants to take care of anyone and anything that's hurt and left behind. (colors for her are not final)
