I see the helmet mod and shortening the two chin spikes, but you mean you also moved those two arcs of spikes on the sides further back on the head? Is that what you mean by moving the "sticky out bits" back?
And did you cast the head before doing the mods? I just find 3D printed resin (and even a few types of filament prints) to be extremely brittle so hard to mod, more brittle than a resin cast.
Yes mate.... did a recast in resin ... as for the sticky out bits I mean the bits in the photo... set them back into the face more hard to see but it was one of the things that bothered me
