I personally feel that the colors you picked for the metal are alright, but the order or placement is wrong. The patina looks good enough, but the bust just looks like its applied with a brush over the metal, more like a camo than actual rust. Try looking up sponge weathering, where you use a bit of sponge to apply paint to get random spots, which can give a very realistic result!
