Nice job man! I liked choice of key and expression. Great attention to detail in phrasing and the coordination with the instrumental track was great. Were you playing the piano while recording or did you track your keys and vox separately? I liked your enunciation and slides that you added to the end of each section. I think I would personally like if you were able to add a little weight (more chest, w/e y'know) as pitch increases in the slides with a crescendo for the drama - it seems like it'd be easy for you to do since it's a slide that's completely in call register, so you can take advantage of that timbre fully for flair imo.

I see... perhaps changing the color of the slide by shading it a bit darker would be something that achieve a similar effect as crescendo. Of course, in an ideal world, we'd have nuanced detailed singing with vowel shading and messa di voce. In time...

And great job playing the piano part while singing then! That definitely seems like a difficult piano part to play well especially while trying to sing.
