does anyone know what this pic is from? http://www.mangago.zone/read-manga/beast_feast/mf...

It looks like this author's work. Sakuragi Yaya I couldn't find a story that matched the picture, but it may be one of the side stories in one of the books of this site. Good luck with your search. ٩(๑❛ᴗ❛๑)۶

thanks! i hope it's not just a random drawing...

It could be the characters from manga Heart Strings by the same author as this (Akira Norikazu). The face shapes are different but the hair, clothes and gun are on point. I think it's fanart so it'd be that artists style.
