Your pretty close. Some adjustments to try:
1. Your filter envelope’s attack stage is creating a horn-style attack transient which I don’t hear in the actual track. Try bringing it down to 0 (or maybe a little higher than 0 to avoid a “pop”)
2. Reduce your filter envelope’s modulation amount. It’s too bright.
3. Add a long slow decay/release to the filter envelope.
4. Add Reverb
5. Enable velocity so that not all of the notes are the same volume
6. Are you modulating pan with an LFO? If so, try adding slow-ish chorus effect instead. That will create a lush and wide sound, and some left/right movement.
