This is my favorite custom I've done so far, the "toughest of the Cobras."
ROC Cobra Commander's body is awesome for a guy in steel armor, and the Sand Viper Head is a great menacing sculpt. Lots of details to highlight with washes, silver and red paint. He really turned out better than I expected and if you have these parts on hand he's easy to make and looks great.
Love that Snake Eyes sling to hold the laser rifle.

Took me forever to post him!
