Interesting take. Second one is a little too sand people for me but they look good.
As far as the story line soil ghosts go. My prediction is that when Kit Lau releases them they will not fit the preconceived notions that some collectors have. It's at this point I predict a decline in the interest of the line.
Currently, a lot of the mechs/laurels proposed look very similar to some MaK stuff....which has peaked interest in upcoming figures.
