I hate to be all jaded about things, but this is the second story I've seen on this boy, and I feel like he falls under the "extraordinary claims require extraordinarily evidence" umbrella.
These are charcoal-based sketches, and for that style of art a majority of the artistry lies in image choice and finishing detail of the sketch (and a little bit in the presketch, though that's trainable if he's using a reference image.)
I would like to have better evidence that these parts weren't just done by an adult, because without it, this boy is arguably a once-in-generation genius, and that is an extraordinary claim.
