My new wallpaper

I've wanted a cute and TF2 related picture for my computer's wallpaper for a while. But it was really hard to find something good since normally, those two things don't go together.

But I think I finally found what I was looking for.

Tell me what you think!

It looks real good, but I have some constructive criticism to it.

It looks nice and original with all the TF2 characters in it and that Kirby has the ability to absorb almost anything and anyone and have its unique ability, but what I am aiming at is the background. The background looks kind of bland don't you think? There is nothing on the bottom half and top of the picture but just either one simple colour or different shades of brown. I have an idea of having a title on the top or maybe something on the bottom.
