The "Dragon Battle" cue occurs immediately after "This is Berk," but it is split into a different cue on the soundtrack. I personally love the roaming horns playing in counterpoint to the expansive strings. This one was relatively simple to make (especially compared to "This is Berk").
The next cue, "The Downed Dragon," should take longer than this one, as it is more rhythmically and harmonically complex, so don't expect anything to be published as quick as this one!
If you haven't yet, make sure to check out the previous orchestration!
