Those are wonderful! I assume the boy in the yellow shirt is Luka. Is his skin green as a result of shifting into the World of Magic, or is this a typical hue for him?
the lad is indeed luka,he's blue in the finished version and yes when he enters into the world of magic all the colours become super saturated and extreme. nobodaddy went a little too far in the render. he's just a darker blue in the final project.
