There is not much bass in the overall mix. Things like the kick and bass guitar should fill out the bottom end more (This might be a monitoring issue, as Bass response of your monitors will cause you to think you have lots of bottom end when in fact you don't). The electric guitars have a LOT of high mid content in the 2.5-3.5k area. This doesn't sound natural to me. They'll sound warmer if you pull a bit of that out and let the lower mids (500-1.5k) come through.
