-armoured tribal head is boring, eyes are too far up the head and looks fat.
-your drawn robot head isnt bad, but a little too cluttered around the mouth, that are would look like a blob ingame
-your shop shows me you dont do much but copy styles without much thought to making it your own.
i see mrama style heads(not the same quality that he makes them) darkjack style heads(also, not on the same level) malvado(dunno why you'd want to) and general sub standard robotic sets...
so a no from me
with a fairly harsh C&C
