Excellent work! I like the coffin (it appears you built it to be partially sticking out of the ground? Great effect!). Your tombstones look very, very nice. I do have one suggestion; the moss on the tombstones looks good, but make sure it doesn't look like it only appears on the tombstones. Scatter some pieces in various well-lit sections of the yard so it looks more like a native plant to your yard. This makes the "seam" between prop and environment blur and lends more reality to your scene. Good job and happy haunting!
I agree, I plan to have moss and vines in the scene as well as on the iron fence surrounding it. I also made some of the PVC candles (red, white and black) with tea lights. I hope for it to look like a very old cemetery scene with some skeletal parts and a 6 foot grim reaper I picked up from Spirits last year.
Great job on the tombstones. Love the way they look old and worn, not broken from vandalism but worn from age. Lettering is great too, makes you want to lean in closer to decipher whats actually written. Just like actual cemetery stones. Coffin looks great too. The second photo shows off the idea really well.
