Journal II: Steampunk

I've added some finishing touches to this bookbinding experiment. Weathered the journal around the edges, stained the paper using tea, rivited the spine bindings and painstakingly cut that damned gear out of tin. (I didn't have the proper tools, so my hands are now covered in blisters and my desk is a mess.)
Am I done, or should I add one more touch by oxidizing the "brass"?
