My honest opinion!.... Here it goes!
I like it, I really do..... but I have some complaints.
----most of this, no... all of this, refers to the song Sleep----
The background "wha wha wha" techno/electronic noice is a bit too loud in some of your softer points. It drowns out your voice at times, and that is just sad. I would either tone it down for those softer points in the song, or only bring it in during the stronger chords/lines (which arnt strong enough for my liking... but ill get to that in my next point). It sounds out of place, that wha wha, i cant put my finger on it.... but i just dont like it.
Also, I wish there was a point where it kicked up a bit harder. Around 2:05 it does kick up with a drum double up and a flute which I thought was a great touch. But I wish you really went a bit more "all out" for that 2:05 to 2:35ish or so. The song sounds too flat, alot of the time, no build up, no climax to a ever popular "After 2nd chorus line freestyle/change in pace" that I hear in 98% of the songs on the radio.
By all out I mean, louder vocals, a higher key in your voice. Temporarly, of course, but just to draw us in for a continued listen. I felt like "okay, it'll get louder/powerful/stronger any minute now....now...now" through alot of the time at 2:30 and onward. The kick up I had in mind occurred at 3:20 instead, which is good, but I feel that 3:20 being a second kick up instead of the first kick up in the song, would be better. it is too late to keep me interested, if that makes any sense. And it was a rather... "gentle" kick up regardless, sounding nearly the same to the initial 3 minutes of song.
I like the tone of your voice (raspy, mellow, dave mathews-ish) keep that.
I also missed not having an expected loooooong key at some point. Almost every song has one towards its finally. (not a kick up... a long key) Usually its like a string of the same word a few times, in a fast song/jazz song, or a words syllab held for a while longer then usual. Sometimes near the end, sometimes after the 2nd chorus string.... for the change up. I felt like you tried it at around 3;40? but i just didnt feel it was built-up-to nor expressed as powerfully as i would have enjoyed hearing.
As always, these are just my OPINIONS, as a LISTENER!, nothing more, nothing less. And it is only based on my listening of other music in the same/similar classes of music.
I do believe you have potential! and i'd like to see where this goes, so keep me posted! us Florida homies need to support one another.
