A little my little pony and final fantasy crossover, which I did for a 45 minute art challenge. Some of you might remember that back in October I did a few drawings of these ponies wearing these exact mage costumes.
These contrive to look detailed despite the non-sharpness of the picture's lines. You are rather good at managing to pull this off. I also really like the different expressions and sizes you gave them, gives each a different air and characterises them well. Good job!
Honestly, those are more or less accurate representations of the Black Mage, Red Mage, and White Mage outfits from throughout the entire series (main and side games). There have been some alterations in various games to have them adopt the look and feel of the setting, but the basic designs, which we see here, have never fundamentally been altered too much. One could look at Vivi Ornitier (FF9), a player in the Black Mage Artifact Armor (FF11), or the Black Mage job (FF5, FFT), and one would see more or less the same thing.
The latter games such as FF10, 12, and 13 tend to buck the trend, but even they still pay some homage to the classic mage looks in some form or fashion (quite literally, in 10-2's case with the Dress Spheres).
