I'd like to see these gals a little farther along before commenting, but the blue could be a little darker. I was thinking of painting up something similar for my Mom's birthday, and after doing a Google image search on Swedish Hussars, I'm probably going to go with the blue or yellow as the primary color, and use the other only for the cuffs, facings, etc. Not really a suggestion, but just another idea.
Cheers,
Jason
