Your hairstyle looks "nerdy" and not in the good sense, "nerdy" style is only good on women.
Don't use game related clothes unless you're with friends and not looking to get people mirin' you, if you expect to do anything with most girls, you'll need some style.
For style, go to /fa/ and look for basic things, like chinos, jeans, t-shirst without trademark name all over it, although it won't matter if it small and some jackets, when you're going to buy them don't only trust what people say, try to use your own taste, even if it makes you look a little worse, you'll be more comfortable with those clothes.
Keep your mouth shut, unless you're talking.
Try not to wear glasses.
And, never stop lifting, you really need it, remenber to control your diet and look for good routines, workout at least 4 times a week and eventually, in some months, you'll look much better than most people, you'll be stronger and, more important than anything else, you'll feel better with yourself.
