i wanted a gotrek gurnison proxy for my army and then i saw nakai the wanderer from warhammer total war and though that could work. i designed him with a robot leg to explain why he is a kroxigor that can only move 4 inches and as a little fluff to explain all of gotreks other rules, his slann had its soul ripped out by a beast man shaman but this kroxigor slayed the shaman before the ritual was complete. the slanns soul was absorbed into a shrunken head which he wears on around his neck. the magical energy it exudes provide the extra protections that gotrek gets in his rules and is the reason no other slann can teleport him like all the other seraphon.
I admit that I don't understand what you are doing there, but whatever it is: it looks very cool. I have mad respect for everyone who can literally model from scratch.
Looks good! I know from experience that a coat of white or grey primer will instantly improve the look of your model for us all
