BG color palettes

So June was mostly spent on AX con and script writing (AX- WHEEE, script- HRRRGH), and since I've pushed this off long enough, this month is now dedicated to completing the bulk of colors and design for my final animation 'Crocodile Crossing'.  So far I tried straight from my head, hated the colors and decided to just do some photo color studies to see what palette I like and don't like.

So far C looks the most promising since it has that light, happy blend of warm and cool colors that I wanted, specially since I was thinking of making specific character palettes as well.
