OniAI : Akiko and friends

One of my past entry for artbook, Imoutomix.
Featuring Oniai (Onī-chan dakedo Ai sae Areba Kankei Nai yo ne!, yup it's the name of the title....)
The artwork was done from a year ago i think.....
_{cause the coloring and the proportion is oh god...}
But hey..
I guess i made an improvement  horray~~
