Lust, greed of humans; pollutions. Well you did a great job in portraying them out through your story. I agree with what you have mentioned.

Somehow, you tend to over-rely on noun as the 1st word for some of your sentence. For instance, your first paragraph consist of 3-4 'she'. Turning them into passive form or reconstructing your sentences might makes it flow smoother.

It's entirely depend on you how to change them though; or I should say I'm too lazy to think about how to change.

Anyway, I enjoy reading.

So, this is basically an introduction to the world where humans have completely polluted the world?

It'd be pretty cool to see some sort of conflict come out of the orb. Maybe there are people who want it for themselves, and she has to protect it? I dunno, some sort of conflict to continue the story. :)
