How to improve my overall appearance?

This is for a teenage guy. What are some things that I could do to improve my appearance? What kind of stuff do I need to bye? i.e. cologne, clothes suggestions, sunglasses, and anything else that might help. If it helps, I'm about 5'11" lean body, thin face, long curly hair that I usually wear a hat so it'll flip out instead of being in curls, I have long legs, I play guitar, ride dirt bikes, and fish if that helps for clothing suggestions. Also, I'll wear almost any kind of clothes as long as they're not completely hideous or uncomfortable, so no skinny jeans.
Also, I was thinking about getting a pair of wallabees, low cut ones, but I don't know which color to get.
I have acne mostly on my chin, jawbone (on sides) and forehead. How can I get rid of that?

You sound fine to me. Haha I <3 Fishing and riding fourwheelers and Dirtbikess.
