The best Feedback I can give is
1) Don’t give up no matter what!
2) You’re following the (not so good) track writers, that are waiting for a M.C/Rapper to make the track come together. It sounds incomplete/missing some key elements to make it a “Composition”..
3) “Try” working without using quantization. The tracks are WAY too rigid, and it’s blocking what could be a natural groove
4) You can get placements now, but you would be playing the $5/$10/$15 Cue Game. You need to steer away from that to set yourself apart from the pack of writers doing the same thing. Work on YOUR creativity, and start identifying YOUR OWN style!!
Wish you well, and I hope this helped! If you would like to hear my work, send me a PM, and I will send you some links..
