I gave this a good couple of listens and I think you really have the right voice for this.
As mentioned by others, the vocal is too loud for such a sparse mix. It could do with a bit of compression on the mix to push the guitars and vocals together more when the volumes of the instruments come up.
I think the instrument doing the high drone note needs to be panned more left and sunk into the reverb more.
The reverb could do to be a fair bit longer/bigger, too. Not necessarily louder.
To widen the mix and give a little more interest in the quiet bits, you could do a trick with the tom-tom. I'd set up a channel with a single slap-back delay, very short, and pan it hard left away from the tom tom. It needs to be set very quiet, on the edge of hearing. Set up a send from your tom-tom to that channel, then set up a send from the delayed channel to your reverb bus. Adjust the levels to your taste. Just a suggestion, but I think it would work very well. I'd send a smidge of the guitar to the delay buss as well, while you're at it.
I like it.
