Hi
I'm not the expert around these parts, but I'm thinking I'd like the kick drum and bass to poke through the mix a bit more. It's almost as though the vocals are used to damp those elements.
Might be something to do with compression... I'm just not sure.
When there are no vocals at all then the mix sounds relatively okay.
I'm wondering if the vocals could do with a hint of reverb... They sound almost dry to me.
On a second listen and I think the bass is panned too far to the right. I think it should be right in the middle, but others may disagree. The kick drum is almost non-existent in parts.
cheers
