I think this image would also work for their Silent Scream.
It fits the lyrics - good thinking and it's presented really well.
I can't say the song is one of my favorites.
I used to be a huge fan of Slayer, and actually Dead Skin Mask was one of my favourites tracks of them. I think you have a cool concept, but not executed as well as it could've been. The green skin just doesn't fit well and looks very B-grade horror movie-ish. I know you can do better!
Mr. Minso, I can see your growth over the last few entries... getting stronger! Nice job! On this one, I think the brush work to blur the background is a little sloppy on the edges. The blur bleeds onto the shoulder line and hair (which is the completely unavoidable!!) The eyes and the mask are awesome!!
