Are these midi drums? If so, step one I'd recommend would be lowering the velocity of the snare hit. Not only is it too loud for the mix, but the hit is too intense for the vibe of the song. That's a pretty heavy rock snare for a soulful, smooth song. The same probably applies to the kick but to a lesser degree.
The lead guitar should probably come down to match when the vocals are going. It's hard to gauge how much (as Robus said, it's fighting the snare), but it is trying to dominate the vox right now.
During the chorus, the balance of pads, lead vox, and bgvox is good.
