Thank you for your advice. I decided to link both melodies: the "cyberpunk" part, and the strings part (with a standart orchestration music sheet). As a result: a new part with both melodies at the same time harmonically combined -even the lead part-. This mix of both parts offers a optimistic pre-ending to the player if we consider that is the boss part of the game. I decided to end everything using different bow strokes strings and decrease util the smallest sound (pizzicato) changing the music tension. I'm glad you like it! ;)
