Change the strings on the first guitar.
Find a catchy riff/hook to play where that guitar just whangs the chords on the intro and every time after that. It's the spot for the big hook...you have three seconds before they hit 'stop' or change stations. Think of Beatle's "Day Tripper". Harrison was and is the guru of that thing.
The references for the tune I hear are Brit Invasion-era Stones...Brian Jones. More twang. Slightly bigger drums. Everything else, except some of the lyric, is a ringer for the '65 UK sound. Just open up the guitars' chunkitude, and try to be a bit more inventive with parts that just sit there. Like the intro that wants to be a big guitar hook. I think the vox is OK. Better than Mick.
I know you want mix advice, but there's stuff before that , that could use some work. I'm a geezer. In the 60's, I used to hear songs exactly like this by every group who want to catch the Beatles/Stones bus. They disappeared, and no one remembers their songs or names. So what y' gotta do is discover what, exactly, is was , that made Day Tripper and Get Offa My Cloud classics. Hook. Vocal and guitar....HOOKS. It's 10 minutes since I listened. I can't remember anything in it.
