I am glad at the responses of Tropical Coast music. I have composed some music for the BGM that has motif of ocean and southern countries so far, but the approach like this is not bad either, is it? In Lost World, I approached it from genres and timbres, but in Runners, it became like this when I set a high value on the mood or melody that I feel in this season. ^^
