I think personally Jann Lee, Eliot, and Rig are the top three best looking guys in the game imo with Diego, Hayate(not so much in DOA6 where he feels a bit washed out), and Brad being close to that.
Jann I think has a very handsome youthful face that almost reminds me a bit of Hwoarang, and i like the subtle scratches he has in a few areas. Eliot has the youthful, almost baby faced look that really sets him apart as the pretty boy which DOA lacks since the men are mostly older. You almost could get him confused with one of the girls if it was just matter of choosing just faces with nothing else to give away who is who
For Rig I think he's like the chiseled western boy toy since he has very a nicely defined facial structure with a bit of asymmetrical touches since I noticed that at certain times one eye is slightly smaller than the other, I think it's the right one where he has a scar above it.
