Art is top tier, did not notice any errors and characters have good color pallets that make them stand out.
Sounds were good for both the city aspects and war aspects of the show. Characters had solid voice actors that felt like good fits for the English dub which is the version I watched.
Characters have depth and make you feel for them.
The first time I watched the series I watched it all the way through from start to finish. It was a bit of an emotional ride but I wanted to keep watching just one more episode until I ran out.
Overall a really solid anime to watch
