The room-size in the reverb is maxed out on your pad sample so I would decrease at about around
40.00
%. Because when it's maxed out like that, it usually echoes throughout the whole song and overtops it. I also would lower the dry/wet a tiny bit. And also sidechaining will automatically turn down the frequencies in the 808 that clash when the kick hits. Use a Gravity compressor for that, and also use a Curve graphical equalizer to swipe out the unnecessary frequencies.
Maybe you could try boosting the percussion frequencies more with the equalizer? I think it would be helpful. But yeah, I don't have much to say other than keep working on your craft and you'll get better overtime. :)
