"All your brains are belong to me" I actually like this, usually borderless sigs aren't too good but this was done in a cool fashion. 8/10
Looks good to me, like they way everything matches well, I don't like giving out ratings cuz I fell i'm not an authority of judging sigs, so I give you a GJ
take it you want the iron amn rated so, its a bit plain and colourless, but apart from that, brushing and blending is nice 7.5/10
Nice renderrrr! Like the brushing as well. Not sure about the bits of tech, but that's my opinion. 9/10
