Sunset Moon rise - Separate

I told you I was gonna scan it so it looked better. .....Well, I scanned it at least. I don't know why my scanner screwed up the green and the lighter orange honestly. Now the hill looks arctic and the last orange looks pink. I tried fixing it with photoshop and tried everything i could, and it either turn out horrible or screwed the rest of it up.

Also, the reason their separate is because i couldn't get the whole canvas to scan so i had to scan the parts separately. I'm tired of fighting with the picture so this is as good as its getting D<
