First step would be to remove the owls and shit and replace them with something badass. I actually might need to replace them just to get more space for books. One time I'll check out action figures or something similar.
Second step would be to get a few posters on the walls. I have one Mario poster, but I'd like to get Paradox posters if they even exist

Third step would be to replace the lamp with a big lava lamp. This will be done, no exception.
Fourth, I need to fill the mini-fridge with Mountain Dew (the mini-fridge in the bedroom is a big part of why I'm so happy lol).
Fifth, maybe I will change the bed sheets for something cooler. You can't see them because the bed's shelved in the pics, but they're a bit generic (warm, though, which is really nice on -30C nights like the last one).
And finally, one day I might replace the curtains with ones that aren't yellow.
And yes, I'm a complete Nintendo dork, I know...my summer bed sheets are Mario Kart sheets.
