Hi, my item was rejected and I don’t know why, can you gel me?
I’d rather not gel you, it’s just not my cup of tea, perhaps other authors will. 
Regarding your track, it was probably considered too edgy, dissonant and intrusive to function well as background music.
Hey 
I think that the arrangement is a little bit poor and not so interesting matching nowdays standarts.
Try to listen top tracks here on AJ, especially in your favorite styles. Try to achieve that quality and sound. Your music must meet the profession standarts and have commercial value for video projects. Also I can recommend to learn on YouTube tutorials, courses more and keep going to write music. Write the music you would buy for yourself.
The quality of tracks on AJ is improving day by day so you have to match this and permanently work hard and learn I believe.
I wish you will get it!
Cheers
