Abomination Raven Skin
The author of the original concept art is kimplate https://www.deviantart.com/kimplate/gallery
The mod from step210 was taken as a basis.
The reason for the existence of this mod was the lack of changes in the step210 mod in relation to the original skin, with the exception of replacing the head, costume color and skill animation images.
In this mod, all possible aspects have been reworked so that the visual part is fully consistent with the original concept art.
I am not a professional artist and have no knowledge of creating 2D animations, so the mod may contain minor flaws.
