So I made some modifications on my original, sculpting veins in the lower arms to match upper arms, and gave it a new paint job, to bolster the highlights and shadows.
head, torso, and upper arms: Savage Dragon. (removed fin, sculpted hair to fit)
lower arms and hands + sculpt to fit: Some jakks wrestler
hips, legs to knees: Marvel Legends series 3 Wolverine
calves and boots: Marvel Legends Sentry
