Spoiler!
So... you have three shadows in the form of the MC, that I'm guessing are his internal narration or his inner voices when he thinks about something, like his reactions
One has the pose of his mother (the one where he puts his hands on his chest), another of his father (looking at the camera with rays coming from the back), and the third is the artist side of him
so... what ARE the first two? the mother pose is his sentimental side? and his father pose is his pragmatic side?
Edit: I forgot about this one but there's a fourth that looks like Riley looking up with a moon on his back, I'm not even sure what this one is either, his impulsive side?.
