5r and red lipstick

The last one works best for me.  It's quirky and comedic.  There's a tension in the others between the serious facial expression and the exaggerated contrast between the blanched facial tones, black clothing and hair versus the seriously red (#ff0000) lips.   The red lips say "comedic" and the facial expressions and stark black-and-white tones say "extremely serious".  I don't think the tension works to your advantage.  That's just one person's opinion.

The last image does work well.
