So I was really impressed with this piece as a whole, I love the deepness and the depth of it, you really do know how to ad detail to a simple structure and that shows off well here. Wow ok this is a pretty good background you have created for pixel art. I love the deep reds and shadows creating images all over the piece. I think this could be a great backdrop for a video game of the horror genre. I love the pentagram in the middle too. I just wish this was bigger with a bit more. So now that most of the review is done her I want to thank you for a nice piece here and hope you keep making us great detailed art like you have done here today.
