Vocals actually sound really nice. It's the synth guitar in the beginning that struck me as odd. Really I feel the vocals are the best thing you've got going here. Work on the sound of your synths more, as well as composition of your intros. Also, enunciate a little more clearly. Que es ser is very easy to muddy up and end up sounding like one word.
Get rid of the vocals and you will go from *** to *****.
Yeah we have made several versions of the vocals and this is the best one, if you can believe it jaja, I guess just getting rid of them might be the best thing. Thanks for listening
Please contact me if you would like to use this in a project. We can discuss the details.
