My initial impression of this drama as i was watching the initial episodes was the resemblance to the Prince of Lan Ling (2013) - masked ML warriors, FLs as extraordinary woman (奇女子), MLs as god of war (战神), war tactics/strategies and peace treaty between warring states. The resemblances wean off eventually as i progressed with the drama and become more attached to The Long Ballad’s characters.

This is a drama of putting the interests of the country before self*, of protecting the loved ones (family and friends) before self*, and a coming of age drama of the four main leads:
(1) Li Chang Ge who despite seeking out revenge for her parents’ death on the Emperor, understands and puts the interests of the country before self;
(2) Ashile Sun who is courageous in his love for Li Chang Ge, loyal to his adopted father and to his people, and who puts the interests of his loved ones before his;
(3) Li Le Yan who transforms from a dainty princess to a princess who understands the needs of, and seeks better lives for, her people; and
(4) Hao Du who once followed orders fervently and coldly to one who doesn’t surface judge and who fights courageously for his princess’ love.

* those are true of Prince of Lan Ling as well.

Besides romance with four couples (Li Chang Ge x Ashile Sun, Li Le Yan x Hao Du, Mimi Guli x Mu Jin, Luo Shi Ba x Xu Feng), there is sismance (sisterly love) (Li Chang Ge x Li Le Yan, Li Chang Ge x Mimi Guli), bromance (brotherly love) (Ashile Sun x Mu Jin, Ashile Sun x She Er) and also touching encounters with kids the two FLs met (Li Chang Ge x A Dou, Le Yan x Wu Ye).

Happy to see Leo Wu again and this time in a lead role, after enjoying his portrayal as the little Fei Liu protecting his master (the ML) in Nirvana in Fire about 6 months ago. He has grown up to be a fine actor.

Zhao Lu Si captivated me and had me rooting for her and Liu Yu Ning’s Hao Du, instead of the first lead couple. I was actually quite put off by her portrayal in Oh! My Emperor, so much so that i only finished the first season and didn’t continue the second season. Perhaps it’s the role. I first saw Liu Yu Ning on the same stage as Xiao Zhan in Our Song. He came across as a good singer. (And i started watching Oh! My Emperor for Xiao Zhan, but never finished the complete drama).

The manhua strips inserted in some key scenes, though a convenient way to cut costs while linking back to its comic source, are eye sores that also cheapen the quality of this drama.

Overall, it is a historical costume cdrama released in recent 2 years that is worth watching.
