Hahaha bless you mate. I'm third generation British-Indian, and can tell you quite honestly that how you look does not matter. If you're a chill guy, you'll find that girls are just into you. I'm not the best looking of men, but I'm not that bad either, and I generally do OK. Just as well as the normal guy to be honest. I don't think I am held back by anything. Don't get too hung up on image, but I will give you the advice I gave my brother: it's a sin to not look after yourself! Anyone can look absolutely great, human beings are beautiful things, you've got it so use it. A good hair cut, good sense of style and a well-looked after physique can go a long way. It's not for girls, it's for you. My little brother generally does well with girls, and since he's got his style and physical side of things together, he's in a really strong position. Dude was doing well before and now he's more or less sorted. I believe you deserve it if you work hard for it. Once you've established yourself you'll have no doubts and you won't ask a question like this again.
Also, if it doesn't work out with this girl, don't let it affect you. It's just one girl. You've gotta have a lot of love for women, this way you'll not doubt yourself and fall into having bad attitudes because the foundation of your intentions are decent and respectable.
PEACE X
