Is this a good fashion sense? If not what should I do to change it?

I wear either dark blue or black skinny jeans, sometimes straight leg blue jeans. either red, black and dark grey check or black and white slip ons, these are all vans. Checkered shirts, sometimes graphic tees, a ralph lauren long sleeve white polo, a drop dead pink t shirt, some band tee's and sometimes just plain shirts. and i always wear an oversized black beanie because i have long hair and it looks good with it. is this a good fashion sense? if not how can i change it and what should i do to make it better? im a teenage boy if that helps. cheers to everyone who helps :D
