The photo doesn't give do the mini much justice. Looking at this model though, I'm thinking that white can be a great color for a Cygnar pallete scheme! As the previous poster mentioned, I'd play up the sword a bit. I'd use some black with some slate-gray veins with a nice silver edge, thus making a black sword look like a fusion of some obsidian rock and steel!
I can't put my finger on what else this model is missing, maybe it's the photo quality. It seems that yellow and steel armor could use something else. Maybe another coat of paint and a bit of mroe extreme highlighting.
Otherwise, a quality tabletop mini.
