Bronze is a real nightmare to depict in miniatures if you want to do it polished. There seem to be virtually no bronze-coloured metallics (no good ones) out there, which is no surprise due to the low demand. So people generally resort to modifying one or other of the golds, either by mixing with something or glazing after the gold is down. What colouring to aim for is then partly up to taste/interpretation, but shy away from anything that makes it looks like brass - totally different colour usually.
More recently (possibly due mainly to the influence of films like
Troy) there\'s been a mini-trend in historical modelling to do bronze as though it\'s heavily oxidised - even going so far as to do it practically solid black. I hate this personally and it\'s clear from the historical evidence we have that this is not how bronze armour looked at the time, but, what you\'re painting here is effectively a fantasy model so this
is a viable option if you like the idea. If I went this route I\'d definitely go with metallic touches here and there, even if only on a few edges, a scratch or two.
Here\'s a good example of how pale polished bronze can be:
