This is good...still some room for improvements.I f i was you i would use a paper box with more "texture" for the walls (to give a wet / dark / scary surface).The "death row" nail is a clever idea.I would place a "power lever" & a nail "guard" some where in the "room".Placing a corner on your frame adds a lot (isolation) but you could use a wider frame to include the chairs legs.Color is good...mysterious / cold.Every thing else is great IMHO & i especially like the electric evacuation!
Best of luck author.

I like your creativity.

I like the "witnesses"

@karaflazz - thanks, yes, I intended on having a red light, an undertaker with a mask over his nailhead, and an old knife switch, but ran out of time. That stuff is too time consuming, and, yes, your pictures were my inspiration for this.

Great dedication to the cause!

It's nice to see that my work inspires others.
