The pics you just shared look good, ghostface. You have a nice mix of props, which I imagine you can rearrange and re-purpose into different scenes each year.
I like your list of scenes for this year! Each one of them is something that I find pretty cool and creepy. And I think it's a nice mix of subject matter too. You can have "realistic" settings with the lab and the asylum bits, and focus on more "spiritual" imagery for the exorcism and spirit parts. And of course, you can never go wrong with a possessed pumpkin patch!
