Honestly there are a lot of options to continue.
Short Breakdown;
Opulenz is cloned to keep the same melody but with an arp. Additionally freq separated, first one more pad like, second one more "piano" like.
Hihat again the same using Tripleoscillator for source. This time plus an open hat (also just first one copied with a notible release.)
The LB is just a melody played on Raspberry Pi Keyboard with differences tried out by listening.
Last but not least a bass following the melody of LB.
*What was surprisingly nice for me is the upcoming delay.
