"The reason the helmet looks large is because of the slimness of the torso on that figure. It's way too skinny."
"Beefing up the body a little would work wonders,"
I modified and added the "fat suit" from the Banner figure. I think it did the trick. It added just enough of an accurate form without making him look like he has a beer gut.
I also threw on he tunic/inner robe to show how that also makes him look larger, and de-emphasizing the size of his head.
Starting to look less superheroish, and more like a real man in a costume. I'm really happy with how this figure is coming together.
