The face sculpt looks great, but surprisingly, I'm not feeling the octopus. I don't know what it is....maybe it's because it's an octopus, but then again, this is Namor.
It's a fairly quite thread, so I'm assuming I'm not the only one thinking this.
While I usually like the XM designs, I think this one has gone too far with the base - it has too much presence compared to what should be the focal point - i.e. Namor. The octopus looks great - but it's just a random cephalopod, not an important character from the Marvel comics. Sometimes a big base works - e.g. their Magneto - and sometimes it doesn't.
