I think Sandman looks ok, but I'm not really digging the swirly sandy portion of it. I don't mind his base being made of sand. As a matter of fact, I'd rather it be made of sand, but more like he's standing in it or something. I've always liked the Bowen's Sandman statue, but the spiked sand ball has already been done by them, so I'd go with a different approach if I were XM. I've seen some pics of Sandman's hand in the shape of a mallet. Two oversized giant hands could work too, I guess.
Making him like this would also be cool:
A giant busted vault door could be the base for him while standing on top of it. Switch out sand hand or switch out sand mallet from normal arms and hands. The mallet hand could be used to signify that he just smashed open the vault door right from it's hinges and now it's just laying on the ground.
One of hands could be a normal hand holding a duffle bag stuffed with cash. His feet or legs could be morphed into bleeding sand over the edges of the vault door. Maybe one of his hands could be bleeding sand onto the vault door base. There's a bit of cool stuff XM can do with this character.
Just you are asking, here are some of my works which I did for XM till today as a fan:
