The bass is very off key to be sure, with the rest of the melody. Change the melodies to be in the same F Flat key that the bass is in, and it would sound SO much better. Since you put some effort in to this, the least i can give you is a 7/10 and a 4/5.
The bass is pretty low, but I wanted there to be a noticeable kick in the song. I very much appreciate your criticism, and will try to improve my song. Thanks.
