Haha. The last time, someone commented on one of my Manu drawings that he seemed to be wearing lipstick.

But yeah, I get what you mean.
No, I'm not committed to the heavy lines, although some of my recent sketches have turned out that way. I don't know why. The thing is, when I roughly finish a sketch, I spend maybe ten or so minutes tweaking things. After that, I just leave it be. I'm not a professional artist, so I've never obsessed about those details.

Now that two people have pointed it out, I'll try to be more careful next time, thanks.
