This is nice! I like the way the wire looks like it's creeping like ivy. However I think you should try and make the whole thing look a little older, there seems to be a contrast going on between the key and the copper wire in my opinion. Maybe use an older key or purposely damage the items your using, to intensify the antique/worn appearance. Adding more keys could be interesting too, like an old key ring!
thank you! i like the idea about the key ring, i am gong to work on that.. and as for making it look older, the copper will get darker over time, and i want the person who gets it to witness the aging of it..and this is a big key, i might make a choker with it with other little keys, but if not it makes a great pendant.. and thanks so much for the critique, it will help me in future pieces!
