HELP - Lineart

This is my most recent pic. I just finished it... Yesterday in fact. I might color it, I dunno. I'll upload it if I do.

My two charas Usarah Demoi and Phillip Glory (otherwise and more commonly known as Phin... Phin is in depserate need of a new name).

A doodle that I liked to much to keep bunched upin my sketchbook
Feel free to color it if you want, just make sure to link it back, I wanna see the finished product
