Before anyone gets confused about my level of skill, I'm just a guy who's struggled with a cheap home recording equipment like everyone else.
Real professionals around here are folk like you who've put stuff out for people to hear. That's the only measure that's worth anything. Me, most of the time I'm stuck in analysis paralysis.
When I say "mix tenses", I'm referring to whether you're talking about things that
did happen (past tense),
are happening (present tense) or will happen (future tense).
According to
all-knowing Wikipedia, "would" is "future-in-past" tense:
"What would you do/Where would you go"
You then change, describing it as if it in past tense:
and then switch back to the present again:
"And people begin to rise"
Throughout the song, you switch from present to future tense.
Now, there's nothing terribly wrong with this. But I think it would be stronger to talk about things in a consistent perspective, if possible. And using the present tense for your narrative is likely the one that will most closely connect to your listener, because you'll be asking them to imagine what they would do if something were to happen
right now, instead of some point in the future. For example:
What will you do/Where will you go
If suddenly you knew/It's too late for your soul
You look around/And people begin to rise
And all you can do/Is stand there and cryYou want to keep
If suddenly you knew... as it is, because it's part of the set up. Plus, you'd sacrifice a good rhyme!
Past that, talking in the past tense just moves the experience you're describing further away from the listener. So keep them in the present.
As for the harmony, it could be just fine. Seriously, I don't know if I'm being overly picky or even if it's just my imagination.
I mention "autotune" because there's a tendency to run everything through it and
suck the life out of it. The little scoops and stuff are part of the country style, and small clashes might be part of the country style. It's not a genre I listen to much.
One of the things I like about
Reaper is the
ReaTune tool, because it shows a graph of pitches. When my vocal goes flat (always) I can see it. So if there's any doubt, you can always bring it up on the scope. It's always better to redo a vocal than to tune it, but if you've
got to tune it, less is more. It's amazing how quickly tweaking and autotuning can destroy a vocal! A little human imperfection isn't necessarily a bad thing.
