前回に引き続きゲーム用エネミーキャラクター12点の制作のご依頼を頂きました。今回も私のペースで、自由にデザインさせてくださりとても嬉しかったです。またよろしくお願いします。
以下案件原文です。

This project is for some additional illustrations for the game. The images can be submitted in the same format as before. I included a reference for each demon/deity if needed. Feel free to interpret them however you wish and apply your own style. As for pricing, the first two (Nyx and Thanatos) will be classified as "detailed", while the rest are "basic".
