My, my, my... So I'm the first to submit...
I choose Misa (and Rem) because I love that (those) character and I think that she'll "win" at the end because she's more... or less bad than Light. Things work better when it's not complicated Hmmm... What else? That's the end of the world but that's a nice end... For Misa, everything must be nice
That's why there is pink stars as explosions...

The picture of the planete is taken on google (just tape planete...) here

That's awful but it takes me time so I submit it^^
Enjoy!
