Hey Zachy, welcome to Taz!
Since you asked...
I will say that I think I like the background of the buttons, but the red on them didn't, right off the bat, make me think of blood. Maybe using blood dripping down them will give you that effect of "bloody buttons" that you want? Maybe making the blood more solid instead of, where in parts we see through it and the illusion of blood isn't so convincing?
I would think that if blood is in your mind while creating this, the first thing you'd want a viewer to think of would be blood, which in my case, I'm so sorry but I didn't.
Keep working at these though, and maybe do some image searches of blood on walls or dripping blood to see if you can fix in your head the image that will shout to all of us...
B l o o d !
