Well, it looks ok, yes the shadows should be softened (don’t ask me how) and engravings would look wicked cool! Well, now that you have the .blend file, you can do as you wish (and tell me how you did it ;p).
ah, error. The holy grale was supposedly of wood, but your grale’s bottom edge looks like its made out of thin metal or smth. Make the edge round , woodish. or smth…
Then soften the edges of the shadow and it’ll be great. Maybe a drop of Jesus’s blood Love the material btw
