Only very young women (teens and early twenties) care about the attractiveness of your face. After 23-25 I can confidently say it is the last thing they look at.

Women of all ages look at height, though. So, if you are over 6', you can consider yourself extremely lucky, people are literally breaking their bone legs with a surgery to grow a few inches.

About being lanky. I was also very skinny my whole life, I could eat anything including unhealthy fast food, sodas, etc and never gain weight. I thought that my "metabolism was too fast", that it was genetic, and that I could not change it.

Until this year where I actually wanted a change and went from 130 to 160 lbs (58kg to 72kg). I'm 5'10 (177 cm). And for the first time of my life, I can wear something that actually fits and looks good on me.
