Technomancer's Sanctum Maker Coin

I decided it was about time to design a maker coin, which I'm also rendering into a logo for my blog and online presence. I figure the symbolism of the design is pretty obvious for my blog.

Half the point of a maker coin is to share it, so here it is!

It comes in two parts: the main coin and the door to be inserted into it. The plan is to print the coin in grey and the door in brown.
