Hi there Friend,,
Please see this as constructive, all here to help…..

You need to consider uploading the file again, Your completely muffled and cannot be heard clearly…

Your vocals need to be recorded sweeter and much much brighter…

It sounds as if the Treble and Mid-range tone controls were turned way down. they should remain at least center….

if off due to feedback,,,,,, record yourself in another room with the mic or turn off speakers….

PS: you do have a nice voice,,,,, we just need to hear it better…..
My Best——SJ
