Blizzard is doing a terrible job at getting us official Overwatch figures and statues. Until they sort that out, there are artists like Mankej doing good work in their stead.
He's made a few statues of Overwatch characters himself, and has recorded progress builds on his YouTube site (he also streams on Twitch) so you can see how they're made.

He's also done Junkrat:
And, most recently, Sombra:
