Ki season themes (not music)

Just thinking while listening to fulgores music that each season seemed to have its own theme (intentional?) season 1- fighter / power heavy
season 2 - nature / organic
Season 3 - tech / mission (mission being more like they have a purpose for fighting or something like that)

Was this intentional or not? Because if you look at the cast of each season they seem to fit these pretty well and even with the music it also fits these themes s1 metal / heavy rock, s2 natural element sounds (pan flutes and what not) s3 techno / rock
