No offense intended, but if that green dino is supposed to be Littlefoot, I certainly can't tell it's him. He looks like Shorty. Also, the characters aren't the same colors in the night as they are in the day. If you want Ruby and Chomper to be in those colors, you should switch it to a day scene. It's great and it's certainly better than I could do, but there are some factors you should take into account when making a night scene. Normally, I would suggest doing day scenes all the time because getting exact night scene colors for the characters is so difficult.
