Snare and kick!

Hi there!

I begun to mix some trance music, and more I try to mix my stuff up, more I find my snare and kick are bad. I’d like to have a tight and punchy/heavy sound. I don’t know if I compress too much, or if I don’t do a must. Anyone has few tips to help me?! Should I parallel compress? work with a group channel? Also, anyone has a good snare and kick samples bundle to share?
