I think the steps are pretty much correct but the smoothness needs work.
For example, we can see on the abs, the base coat (regular skin it appears), then a couple shades of a brighter skin tone, which is fine. However, some glazes (ie. many layers of very thin, base coat mixed with the whiter colour) on top of the area should make it appear smoother.
Right now the colourings are right (prob needs a couple more darker areas but you get the idea), but they are adrupt and should try to make them smoother. THe same with the skin on the other minis as well :D
THe gold appears to have silver hilites on the edges? nice...maybe some washes moving closer to the hilt for shading...
