There were a couple high school non-cartoon-related drawings that showed at the very least
some modicum of potential:

But then of course, his pampering parents overpraised
anything he did no matter how shitty, and with Chris being both autistic and a hopeless imbecile, he couldn't tell the difference between examples like these and crap like the Sonic Totem, so he took the easy path of thinking his shittiest, but way easier to make "art" was the way to go.
Even outside his own ego, Chris sense of quality is really warped and pedestrian, he thinks horsie cartoons made for preteen girls are the pinnacle of human creation and that McDonalds is gourmet cuisine.
Chris couldn't appreciate quality even if quality bit him in the dick, so he doesn't see anything wrong with his doodles and therefore doesn't feel any need to improve (he did somewhat marginally improve since he began drawing Sonichu, but just out of practice, not because of any conscious effort. Still draws like a blind quadruple amputee covered in bees, though).
