Check out this amazing CGI renditions of Superman, the man on steel by ~alejit0 of DeviantArt. I usually don’t like the cartoon-looking superman and prefer the more serious superman, but this is truly impressive artwork. The things you can do with 3D Studio Max are quite impressive!
You have nailed it. The ideal and original Superman look with a broad jaw line.
I really like the 1950’s cartoon look on the art
