Representation matters
One of my favorite aspects of magic has always been the art. As a kid, I had three or four cards I found at a bus stop, I'd stare at them for hours at a time (pre-google times). Imagine my surprise as an adult to find the art lacking.
I don't see any fat people. Every planeswalker is buff and/or lithe. Most drawn humanoids have the same shoulder and hip ratios, and they all look like olympians. Surely the use of magic would allow for a powerful caster who isn't quite so.... barbie and ken.
I have no complaints on dwarves or hobbits.
Jaya is one of my favorite planeswalkers, she is not included in my criticisms. Oko was also refreshing, but still hyper lithe.
Please bring some more body type variety into the world of planeswalkers.
