Come to think of two things seeing this.
A) the paintings Maria's mother made in the note event thingy (she's still trapped in the statue so at least that part of the plot lingers on)
B) Plato's
Allegory of the cave
Reflections: The painting is on a old torn up piece of paper (or possibly parchment).
There's a grid pattern in the background that is not a part of the painting itself.
If the black dots are Orbs, there are at lest 2 more than we have in the game today.
On the left side there are the mirrored letters VIE (life in French) and what could be a Chinese (?) sign on the opposite side.
I agree with Alien - I see screaming faces with fangs in the foreground, rather than a bunch of Santas worshiping pieces of coal (even though that would make helluva plot for a sequel to The Grinch that stole Christmas). The dark shadows could represent burning ruins, and may suggest an apocalyptic nightmare scenario.
I can say this for 99.9 % sure though: this is not the work of a kid.
There are far too many overlapping art techniques used, and several different brushes, crayons and pens used in a most elaborate way. The layout in the picture and the use of contrast colors suggest that this in fact is made by someone who's quite familiar with art work. Even though the style may appear naive at first glance, it's definitely Expressionism.
Though, I'm certain this wasn't made by any of the established artists in Entropia (Ernst Billgren, Mark Kostabi, Kika Karadi and Mark DeMuro).
