Nice to meet you, Amino Dopuri. I contacted you after seeing your wonderful sample illustrations. I am creating games for adults. I would like to consult with you about two character designs for the game. The final image of the character designs will include three-dimensional drawings, detailed descriptions of accessories, and rough impressions of impressive facial expressions. Please check the attached documents for details of the content. After checking, I would like you to give me an estimate of the cost per character design. (After discussing the content and checking the portfolio, there was a request to change the characters requested.)
