I do not own any of the below artworks. Found them all on pinterest. 

Sigrun

6ft4

Her hair reached her chin and was a silver sheen like that of a sword. It was straight and styled as a like a bob cut, but her serious and authoritative face dispelled any hints of childishness. She was tall, over 6 ft and held a shield and spear befitting her stature. With her partially armored attire consisting for metal, leather, and the rest of her robe like clothing, she revealed a fit and taut figure. 

She would be a combination of the two above, with the 2nd’s attire, but the 1st’s hair and wings. 

Nix-She is a rock

Laos-she is a snake

Ciel

From the magic circle, comes a girl. 5 ft 11, she had dark and dark blue hair. Really she could have been an elf and I would have been none the wiser due to her pointed ears. She had a fancy/noblish outfit with her coat, vest like attire, and fashioned skirt, in addition to her jewelries all having a cross shaped similarity. The only key factor differentiating her from an elf were the star or cross like pupils she held. Her hair done as a pony tail, and her demeanor was elegant but strict.
