I'm glad you liked it.
About the mode thing, the constraint was avoiding the use of Ionian, aeolian, dorian or pentatonic. That's why I chose lydian and I tried to explore it at its fullest. The piece modulates between different lydian tonics. There's also some other modes used in the track but for specific passages, so they're not explored, is just a one chord thing to create some tensión, like melodic minor at 1:09, mixolydian b6 at 1:41 and altered scale at 2:28.
While it's true lydian is very similar to plain major because there's just a one note difference, the feeling it's brighter and the mood is different.I think it meets the requirements but maybe I should have gone with a spicier mode like a mode from the melodic minor scale as a main mode. But I felt lydian al lake go really well together.
