Welcome to the Yards! Great community here; you'll love it!
Very nice approach: you've utilized soft goods quite well here. Soft goods are often used sparingly in most of the customs out there, but you've gone more extensively into this area and the final product looks great. I love the realism that you've created here with the 'leather' straps and the frayed hem on his robes. Very nicely done.
IMO, the pack is the best part of the Mythos figure and you've done an excellent job of replicating it here. You've obviously taken great care in choosing parts that most closely represent the pack on the statue.
