Can't really explain why, but I always found left far more appealing than right for some reason, and it's not even the background that is in question. Right for some reason feels more "plastic" and less "alive" than the other.

Not really an artist, but just curious because I keep saying a lot of "plastic artworks" like right everywhere, while left ones seem to be rather rare - unless it's from 70s,80s,90s etc.
