The shoulder may be narrow, but the last time I saw him, Sir Ian wasn't very broad shouldered himself.
I hear ya, Kit, but it's the narrow shoulders that are making his noggin look even bigger than normal. At least I think so. Perhaps if the headsculpt was slightly smaller in scale, it would fit in better? I don't know... Again, maybe in person this one looks better than in pics.
Still, I think the outfit is amazing.
