Backgrounds (added more images)

So. Backgrounds. Well I found some images which I thought would show a good idea of what I want. I was talking with Tarn during class the other day and found that our ideas were similar again-.-'' So I've decided to change my idea.
Here are some images:







At the moment I'm thinking the second image would be a better option as Tarn's would be set out in the open, so I'll try drawing mine inside the cave. Hopefully it'll turn out alright.
