1st track.
Try to put a limiter like vintage warmer on the drum buss/group and boost for ~ 2dB, then bring down the volume on the limiter for ~ 2dB.
But do it only if you have that amount of headroom on the drum buss. This probably makes no sense but it groups up the drums really well for some reason.
Try also putting a saturation plugin on the drum buss too (be careful not to overuse it).
Also try to high pass a bit more on that *punching on the sides* sound in the drop.
2nd track.
Love the atmo hits and effects but the drums are really lifeless imo (saturating also helps).
3rd track.
Great track, love the melody in the intro. Only thing that bothers me is that on hihat sound in the drop being right in the center when it comes to the stereo image. Try panning it to one of the sides.
4th track.
Love the intro again but that crash is the only thing panned all the way too left, bring some more elements around it.
