Got the Megatron helmet and I'm not quite as impressed by it. Despite being bigger than Optimus, it won't actually fit my head unless I really wedge it on and jam my nose flat. There's a rubber pad that's supposed to rest against the bridge of your nose which I could probably yank out and get a tiny bit more space, but it wouldn't be comfortable to wear for any amount of time. So I guess it'll be for display.
Also, I'm not sure why they gave him the extra angle on his "cheekbones" compared to the animation.
It doesn't come across quite as much in pictures, but irl it's like he has bags under his eyes. Maybe I'll at least paint the black parts.
Edit: Did his eyebrows and forehead (though opted not to do the full uni-brow).
