Well now we know that your sense of humor didn't just develop later in life
I'm going to provide feedback simply as a viewer as this is not my genre. Both images "work" for me but for totally different reasons. With the B/W you achieved the result that you intended. It has a very mysterious, maybe even sinister feel to it. I'd expect to find human remains buried somewhere on the grounds
On the other hand, the warm tones of the color version remind me of an old hunting camp or similar where hot coffee and warm hearts await.
A good example of how different color and b/w can be.
