808 sounds really good, the synths compliment each other well. Snare could use less reverb. Hihats might sound better a little louder. I like the lowpass filter towards the end. Good beat
Your 808 pattern sounds really good. The notes of your 808s are dope. The melodies are good too. The whole mixing looks good in my opinion. I think the filter you used around 2:00 is too long. If you can use it for just 8 bars it's just enough. But overall it's a great beat, great trap beat. Rappers will like this instrumental for sure. Good work bro!
