Cool, it all works well together. I don't know if I'd even have noticed the kick without my new monitoring headphones that have good lows. It's partly a dynamics problem where it sounds like the same exact velocity every time also. I'm not sure if you can go in and adjust your volume and dynamics like in Steven Slate Drums (through the Kontakt mixer), but I would try that with the kick drum. It may be best to just bounce the drums separately than try to change the entire mix or send them to a preview bus and EQ that differently, so you have a blend of the original tracks and some added highs. Sometimes even trying a different kit, bouncing that and bringing that into your preexisting mix (as well as bounces of guitars, bass, etc; you can blend in differently rather than change the original ones). Some kind of magic starts happening sometimes when you keep your first mix and add more tracks with different EQs and things. Can create a lot more depth and fullness without making the ears jump around and focus on individual drums and things (or for example, widening guitars can be a bit too obvious if you don't blend in that effect with your tracks that just have some simple panning and EQ).
