Computer Room Design

Ok, so in my home we have a family room which is also a bedroom for three people, and it has a computer desk in here. The walls were painted a coral color ( I hate it) and the room is basically more of a bedroom then anything. It seems to be the spot where EVERYBODY wants to hang out, because it was a family room. ( I will provide a picture only to SERIOUS people who have ideas) There is a lot of clutter in the room, because there is no space to put clothes up. We have one dresser that is already filled up with the children’s clothes. Pictures will explain a lot better. I want the room to feel homey. Inviting when people come into the room. This room used to be a two car garage that was converted into the family room, so that can give a little bit about the size of the room. Just send me a message for the pictures. I would really appreciate the help thank you!!

okay, so I’m 14, and I’ll be 15 in 1 month and 24 days
i want to paint my walls mint green and do one accent wall with black cheetah spots
what bedspread would go good with this
I’m trying to stay with the black and white theme
I’m spray painting my bed [wood] and computer desk black and white
so, any ideas?
or better designs
i have to keep it like this for a while
and it has been bubblegum pink since i was 8, so im tired of it
links/pictures would be very helpful
please and thanks!
