Hello! Im familiar with both DDLC and Touhou, but it would be preferable to get some more info on the project you're working on!
Well it's a visual novel mod with an open world experience, we will especially art need for 5 original characters (4 humans and a phoenix) in a visual novel sprite and chibi style, we're looking for an unpaid artist since it's a free mod,
here the trailer of the previous mod to give you an idea https://youtu.be/6lNp3pMwbUo
and here are the promotional illustrations for DDLC x Touhou Project: Mystical Verses.
