That article you linked to was what inspired my attempts at conversions!
I like the variety of re-posing you showed in the picture above. The conversions turning spearmen into archers worked quite well. That’s one I haven’t tried, but I might give that a try if I expand my EM4 orc archer unit - the standard plastic archer is a good figure, but a bit of variety would be great to have. Thanks for sharing pics of the modified figs!
