I've been playing with him extensively, and I'd kill for a scale morph for his shoulder area, to make the shoulders wider. I tried skaling the individual groups (chest, shoulders), but results are... well, let's just say he doesn't look healthy.

Also, his feet need an arch. They look like a case for a physical therapist.

I know that it's not a corrective morph, but in case another content developer reads this, I'd also kill (or at least pay good money) for a veins/muscular striations displacement map, like the one Apollo Maximus has.
