Help from my design savvy friends

There is a Supernatural design contest and Imma enter. The design will be used on their merch, like shirts, mugs, etc. The themes are Family Business, Hunting Things and Saving People, so I've gone with a family business sign crossed with a Ouija board, but I'm not completely happy with it yet.

Any thoughts/ideas/suggestions are very much appreciated!

( Work safe, duh! )

Tweaked!

Thanks for the advice, everyone! Here's what it turned into.

(  Final? version )

I'll wait for your secondary advice before submitting. <3
