I think that there's nothing wrong with complementing someone's looks, and I get that everyone expresses themselves differently.
However there is a line between complimentary and creepy, to me if I got a message like that and I was a woman I'd be a bit creeped out tbh. Just like I would be creeped out if a woman said to me "I saw a photo of you yesterday, I can't wait to play with your Penis" it'd be like "okay, stay away from me."
A funny thread though.
