The Edge: Dawnfall - Demon Shrine - Blood Altar

Hey guys, after printing out the Crystal Patches designed by "edgeseeker" I decided to remix my own faction shrines for the board game The Edge: Dawnfall. I'm not very good in modeling, but a wizard in copy&pasting.

But I somehow feel like this design looks a bit boring compared to the other ones now. What do you guys think and would suggest to add to make it look cooler?

/edit: minor update to the 3 round circles in front. After printing there is a high chance they disappear due to their small size. I hope it now is big enough.

/edit2: minor update to make the pentragram more visible, which sadly didn't helped much, but at least you know got some room to paint it on and some more material behind the coins to make it easier to print.

This one here is the Demon Shrine - Blood Altar.
