Thanks!
Yes, the left arms of those are best concealed behind shields, but as I constructed a band of light raiders, only a couple actually carry shields, most do not (sacrificing protection for speed).
I hadn't really noticed the knees, as they all carry slightly baggy pants with all kinds of leg wrappings, but, yes, you may have a point there, too.
At least they are dirt cheap, making it possible to create the rank and file of many Dark Ages armies, and I think they look better in numbers, where the beholder sees a body of men, not focussing on the individual model. Never the less, I am going to use them for my skirmish warbands, too, as I like the price (I really need to start spending less silver on gaming, as the girls now are of an age where I want to show them Europe during our vacations, and travelling is not cheap!).
