Wow. I love the whole thing! Professional work. I would be glad if you win...
Since you specifically asked for "bad" things pointed out (even tho I don't think these are anything important - small details, really) there they are:
The 4 Suns of destiny: 0:33 - strings second chord is too abrupt.
The sun of water: 1:34 - the change of mood is quite big for me.
The sun of start, wyvern Battle: I guess it was a maybe a goal but brass VS piano in this way sounds disharmonic.
Generally, I don't see much of the jams theme in the music.
BUT!
Overall, just wow. So much high quality music in such a short time. Incredible! :)
Just one question at the end: Who made the artwork? It really fits the music and I like it a lot! (EDIT: Ah, found the videos description now 😁)
I totally want to hear more of your music!
