I've always wanted to do a custom of Mercer. He's always fascinated me, being an AWOL Cobra who joined the ranks of the Joes. Actually, all the Renegades were pretty cool, hopefully I can do customs of the rest of 'em. Anyway, the Jurassic Park head fit the bill, had to add the scruff to make him seem tougher and older, and I tried to cross out the Cobra tattoo but I didn't use a fine enough brush--good enough, though. Also, it makes sense to me to use as many Cobra parts as I could, as if he's re-colored and customized his old gear. Thanks for looking.
