The tattoos hurt his look a lot, as does the weak forearms and whatever is pumped into his arms. Hamstrings are unusually strong compared to quads, and calves are virtually gone. FLS and other shots look weird because his delts seem to really flatten out. Back is still sorta there.
IMO Kevin looked better because his upper body was basically back to where it was when he retired. Flex's 2003 look (even though a different class) is in another league. Hell even his rushed 2002 prep is far superior, although you can see shades of this look in that (last pic)
