Hey there, thanks for entering! 1, 2, 3 and 5 look absolutely fine but 4 looks more red to me than bronze or gold, and it's not clear whether 6 is supposed to be gold or silver I'm afraid, so I won't be able to include them in voting as they are :/

ETA: On second thoughts, 6 is fine, it's just 4 that doesn't look 'medallic' to me, sorry!
