>>10611357I thought the same thing about it not being Lego initially, but I think he does something weird to his pieces with salt or some shit-- didn't look much into that part.
But in some of the other images, the other, more-obviously-Lego pieces also show that texture.
And actually, now that I look at this again, I guess you can kinda see some smoothing on the ass piece there where it looks like it's been treated. The edges don't look as sharp.
