I love that first lip color, the whole look in that picture is perfect, haha. I don't ever wear lipstick or anything though, especially not that dark. Cause I don't really have anywhere where it wouldn't look out of place, and it just doesn't look good on me, it's very hard to pull off. :/ But I really like the look of dark lips, on the right person it can be stunning. Dark eyes can look good too, but it just seems really common to me.
Neither are very natural, but that's kind of the point of them, I guess. Dark lips *can* be, if it's more of a berry color, or if the color in the pic was more sheer.
Personally I go for more of a dark eyes look, but I usually do more of a cat eye thing than a smokey eye.
The lips look pretty in an artistic way, not very sexual maybe. The eyes look raunchy, maybe some guys find that attractive.
Both are unnatural, but the eyes picture is more common-looking.
I don't wear either, I have a fair complexion and hair-colour so both would be very unnatural and with the dark lipstick I would remind people a bit of a vampire. But if I had to choose, I would mind least looking like Rosalie Hale.
