20/M - Looking for a bit of advice on facial hair and glasses

So I assume you read the title. In the last couple of years I've done some things which I think improve my look (braces for teeth, cutting extremely long hair).

Still, I had hoped for opinions on some things. I've had the chin-scarf for several years now, and only shaved it off once while I was still in high school. Hated my look then, so I'm too scared to just shave it off now on a whim.

Also, I've had glasses for years, but have thought about how contacts might influence my looks.

...and, of course, am I ugly? I mean, I admit to having large confidence issues, but the love-life has been sort of stagnant for the past year or two.

(that last one was staged with no glasses for some reason)

I'm at 5'10"and about 165lbs. I hope to lose about ten or fifteen of those in the near future. Freshman year of college ruins everything.
