Redecorating my room? Hey, i wanna redecorate my room cuz it doesnt suit me anymore....

Hey, i wanna redecorate my room cuz it doesnt suit me anymore. Im a teenage boy and involve ideas... i be thinking a bunch of posters everywhere? idk is this gonna look to busy? any ideas would b great. O ya i own a big dresser, a big tv, a bunk bed with a futon on bottom, a desk, a skylight and a small closet. Um... i like guns/army, kindof cars, sports, the usual. Any concept would be helpful.
Answers:    - you could mount a made-up gun on the wall?
- army print bed covers?

if you want posters, a line of them along the wall would look neater if you're worried just about them looking busy but most boys rooms are messy/ busy so i think you can obtain away with it! haha

and i close to the idea of painted stripes (mentioned above) on a wall (like a cars paint position maybe?)
It would be spruce to paint stripes on the walls with basically a few posters. I think too abundant would look busy, like you said. Rearrange the room to fit your style, so if you close to open spaces try puting things along the walls and departing the middle open. Just think like that. Sorry I'm not much give a hand.
