Still not quite perfect.
looking at it on the sphere, the eyes look a bit high up, makes the top pinch up a bit.
if i had seen a shot with it on the sphere, i would have suggested lowering the eyes or just that top piece, to fill in the gap between the plate and the eyes.

but the improvements youve made on the metal shading and brightening of the eyes are noticable.
the metal looks much more like metal and the eyes are more of the focus now.

well done

Head is ok-ish done. What I totally don't like is that you've been totally unoriginal and basically drawn it as it is without any custom design adjustments you probably could've and should've done.

What I also don't like is back metal plates. I think it's kinda bad design and don't look so good (button with copper cooling is kinda nice, tho)

Ugh.

Tell me, why would he alter the appearance of Megatron to be original? That would be like requesting a spiderman head and him making it green.

I think this is one of your bests, besides my dog head of course.
