Indeed, even on Fantastic quality I had the same impression that it looks like a flat disk. I'm not too worried though. I assume that will change as the game graphics are later refined.
Speaking of the auras... I want to say I'm a little disappointed they chose red. I don't know why, but I always appreciate when designers go out of their way to utilize complimentary colors. Complimentary colors are exact opposites on the color wheel. Purple with yellow, red with green, and blue with orange. Many graphic designers choose to have characters with complementary colors to show a certain amount of opposing force or to emphasize the differences in personality. A great example... in the original Star Wars trilogy, the Empire's spaceships use red lasers while the Rebellion uses green. Or... Sonic the Hedgehog is blue while his sidekick, Tails the Fox, is orange. I was really pleased that the game designers gave the girl a yellow dress because it's the perfect compliment to the sorceress's purple outfit. But then the sorceress has a purple aura and the girl has a red. What happened?! It would be different if the red corresponded to the robot somehow, but no such luck.
