Wittians I need your help!

I'm moving into a new room, that I have free range with, I have so many Ideas and I just can't makeup my mind! Please help! So many ideas going through my head! So I have these ideas, and I need help deciding! One of my walls is going to be a creative wall, now I'll tell you what  I was thinking! 

Idea #1: A huge city skyline of tops of buildings and stars, think the effiel tower with little golden silver stars dotting the sky, Accented by the lights I'll be hanging around the top of the ceiling. Very detailed to set the mood of Paris and love.

Idea #2: A big collage of painted things I love, A TARDIS, with the doctor peaking out the door and a painted galaxy behind him as it floats through time and space.

Idea #3: A big tree, painted in all black with photographs (Stuck to wall) of all of my family and friends. then behind the tree I'll paint Little signigant things that I love, owls, stars, maybe a silhotte of a girl near the tree, with a camera around her neck and a journal in her hands.

  Idea #4: Section off the wall into four parts, each with a murial that is about me.   Comment ideas? I need them.
