I used to build a lot of snowmen as a kid, and while they weren't as fancy as this guy, it does strike me as a very lifelike snowman

I'm not in any position to comment in any modeling technique--and it looks good to me, as far as I can tell--but the composition might benefit from some random snow located at the 'feet' of snowman, like.. leftovers, and signs of the kids (or big kids) who built it.

Though as a snowman on its own terms, it's a pretty damn good job
