First don't apologize we're here to gain some experience. Not bad at all, its a interesting idea you just need to mix up your arrangement, try to change some rythmic patern so we're not stuck in the same loop for 2 mins, you went full modale on this one, next time you can probalby try to change some chords and I don't know what daw that is actually XD but I feel you're a little limited so its hard to arrange MIDI playing witouth sounding too stiff if you can try so make it more "human" it would make the track look amazing.
