I'm male and, judging from those pictures, I'm around 25%, maybe slightly under. I gotta be honest, I'm not happy with it, but my girlfriend loves my belly for some reason, so my self-esteem has gone up a wee bit. Maybe I should just be satisfied with the fact that I went from 40%+ to around 25% in half a year and have managed to maintain the new weight so far...
Anyway, I'd prefer to be within the 15-20% range, but I don't think I have another diet in me at the moment.
Regarding females, I'm definitely into 25-30%. Heck, 35% is alright too... anything above would probably not be my type, but anything below 25 wouldn't do it for me either - I'd probably get a bruise or cut myself on protruding bone structure while trying to cuddle a woman like that.
