Alright man, Ill be honest with my personal opinion-
I listened to 3 songs.
The good-
These parts of the recordings sound like your 'sweet spot' in the range youre singing in:
Hallelujah: 2:20-223 & 2:27-2:29
Yesterday: 2:28-2:33, the highest part of 'yesterday' when it goes 'in yester-day-a-a-ay'
Stay with me: :45-:48
The bad-
Hallelujah: 2:37-2:41
Spots in the others.
The ugly:
You've got some power behind your voice in certain parts, but its not there a lot of the time. You sound sort of nasally? Thats the only way I can describe it... that might* work with certain niche kind of songs or styles, but not majority of songs and styles.
It also sounds like you're 'working' a lot of the time or 'trying'. Idk if this makes sense but have you ever heard someone singing and it just sounds like it flows out effortlessly? Like theyre not really trying it just comes out?
Try going through these 2 or 3 times.
The first one gets your breathing right and opens your voice up.
The second one deals with tone and projection.
Itll take a good 15 mins to do these right, and you may sound dumb while doing them, but if you do them right you will likely notice a BIG change in your voice, even just when speaking. Youll also be able to carry notes longer and project louder without trying very hard.
After I did those I was like whoa. Its a pretty dramatic before and after difference and it may help with some of those problems i spotted when listening to your recordings.
