I absolutely fell in love with The Legend of Korra when I watched the show, and I really like how despite being in the Avatar The Last Airbender universe it is still unique and different. In ATLA the settings revolve around around mostly nature or villages/cities that have various types of traditional Asian architecture. Although the art style is the same in LOK it was great to see the style in a more modern setting that is different from the original saw. The creators and the artists got to unleash all of their creativity, which allowed for some awesome things, both in the story and in the art. I really liked how this book highlighted how hard everyone worked to design things and much thought was put into every single detail.
One thing that I find particularly cool is how the machines and mechanical objects were designed. Obviously in ATLA there aren't that many machines, and the ones that do exist are often a bit simpler, but everything is so industrialized in LOK that everything looks really different. They had to design cars, airplanes, and large ships, and even though those vehicles didn't get that much screen time overall, they sill were heavily detailed. I can't imagine how long it took for everything to be drawn, and then those drawings had to be approved and revised before a final design was ready to be animated. I struggle with drawing those kind of things, so it seems way more impressive to me than it probably is.
I thought that the backgrounds were incredibly beautiful in this season, and I think it's better than the ones in ATLA because most of them are much more detailed. As I mentioned before, quite a lot of ATLA takes place outside, so as a viewer I didn't pay as much attention, which is entirely my fault, but it goes to show what viewers focus on. With LOK I payed so much more attention because it was so flashy, which is the general vibe of Republic City. It's easier to draw a background of a mountain than I city with specific architecture and I very specific feeling. I loved how one of the creators (I don't remember which one) was constantly saying "this one is my favorite" for every single background painting that was showcased, which was pretty cute.
However, my favorite parts of the book was when we would see the characters. It's cool to see the characters I know and love are brought to life before my eyes, and I liked seeing how they looked before their designs were formalized. Although I really like the designs that are in the show, I did see some that I also loved. I particularly liked seeing Korra's old designs, because some of them were so amazing. I honestly would have been completely happy if Korra had been really buff lol. And of course, I also really liked the fashion we saw, which wasn't just inspired by the four nations, but also included elements from the time period it was based around.
I have the other three of these books checked out, so I will be reading those as well. I thought this one was pretty great, although at some times I got a bit antsy, but overall it was great. I loved seeing how much this season incorporated visual elements taken from the industrial revolution, the Great Depression, the golden age of Hollywood, as well from the steam punk style. It all blended together incredibly well, and I thought it was visually amazing. I think this might be my favorite season of LOK art-wise, and this book makes me confident in my answer.
