Here is my current room:
To treat my room, I will buy two packs of Roxul Safe n' Sound (3'' thick) because it is the only one available at my current location in local stores. The problem is that I don't know if I should buy two packs of 8x 24'' large, two packs of 12x 16'' large or both (one pack each). I do not have the money for three (that's why I go for two packs). Here are four pictures of potential setups, I want you to choose the one that seems the best for you (post the letter and explain why if you want). Thanks!
P.S. I did not include the cloud in the pictures because it was hidding the desk (but keep in mind that there's one).
