It was really hard to finish this one but I promised
that I would make it for her so here you can see a result.
It's a chara design of Nyx, Thanatos, Hypnos and Nemesis's mother. She's not from any official books or games but my own vision of a goddess from Greek myths. Since there isn't any good information about her look or personality, it gives a great opportunity to create the character the way I wanted.UPDATE:
I forgot to mention some tips about making Nyx's hairstyle. Many thanks to ~edylisation
who gave me some nice suggestions.[link]
The link provides some useful info. Moreover, in case of Nyx, as ~edylisation
stated, hair should be twisted around the horn-shaped styrofoam which we originally covered with glue just to prevent hair from falling.
The other chara design:
Media: mechanical pencil, Adobe Photoshop CS3
