Yes, it is very repetitive. You should use more variation on your melody. For exemple, you play these notes : A, G, A, F, E, D. Try other notes, even if you keep the same rythm pattern. You can play something like : A, G, A, F, E, D .. A, G, A, C, C, D.. B, C, B, B G, E.. There is an infinity of possibilities
I guess the piano and the lead instrument are coming from musescore. Musescore is great to write partitions, but it's really not good for sound quality. Try to compose your melodies (Or import you midi file from musescore) on FL and work on dynamics, add some effects to your instruments,bring it to life.
Keep putting efforts on your music comprehension, learn how to make good harmonisation, watch video tutorials on youtube about FL, equalization, mixing, mastering, learn some more music theory. You can only get better!
Continue to improve your skills, and I'm sure you will finally pass trought the scouting step. Good luck to you!
