i have been asked about how i do my front-facing feet, so here it is:

1) easiest way to make a front-facing bare foot into a front-facing boot-foot. simply cover the toes with insignias, and color them appropriately.
2) also easy, but doesnt always work. mask a female boot-foot to a rectangular insignia, so half is showing, and place another flipped one under it, and cover the rough spots with insignias, like in number 1. the crappy upper portion should be covered by the bottom of the leg.
