This post is pretty much a repeat of the HO scale Modelu crew. O scale is so much bigger that these are much easier to paint! Rather than post each successive layer I figured it would be better to just show the finished product.
Even in this larger scale I'm finding the details on these miniatures to be a bit to fine. While I'm not a huge fan of exaggeration there is a point when exaggeration is absolutely necessary. While the folds in the clothing is excellent, any other "softer", "smaller" details are lost at this scale. In particularly all the definition in the face has been lost, although its better defined than the HO versions. A sculptor would be able to exaggerate facial features to give the face depth and character. Difficult at this scale but I have seen sculptors do some amazing things at this scale (I have also seen some abysmal failures).
