I'm guessing whoever designed this case was either lazy and/or has never played the Legend of Zelda series.
At first glance, this looks like a beautiful case. The color scheme is great and the design seems to match as closely to the Majora's Mask Edition 3DS XL as possible, without stepping on any toes.
The problem is when you look just a little bit closer and notice that the designer simply created half of the design and flipped it to make it symmetrical.
This would be fine if it didn't..
A) Strongly distort Din's symbol (at the top, in the triforce)
B) Double Nayru's symbol (the bottom two)
C) Completely replace Farore's symbol.
I could be nitpicking but I would assume that 99% of the people who buy this case, buy it because they're Legend of Zelda fans, and those 3 symbols are a huge concept of the series.
If you're one of those people that say "Wow, who cares?", then ask yourself, why are you bothering getting a Legend of Zelda case in the first place?
