I agree this is not typical Waterflame, but I think that your talents work well even under the rock genre. The guitar background definitely gave the song the epic feel, and with superior headphones, they made me get up and jam out to it.
I'd say keep experimenting with guitar, but don't simply give more parts to it, just switch around 1 guitar among background and melody. Obviously your forte is the creation of melodies, so try to incorporate the guitar. Maybe look at guitar solos from a band like Rhapsody of Fire, that incorporate the lead into their entrancing music.
Your song made me feel like a champion of my patron god POSEIDON. Please continue the tributes!
