This is Sleet. He is a superhero who uses his power over ice to create weapons to fight with. Before gaining his power he was a champion Marksman, so he tends to favor creating functioning guns/rifles out of ice.
Nice proportions but he's too much Power Ranger for me, if he's an ice dude maybe you could make him to look like ice and then the armour could be metal to break the model up, either that or rocket boots/rocket backpack with the current design.
