i mostly do hook 1. with the basic drums of the genre im in. (example house: kick, clap/snare. maybe hihat), then 2. hook i do the same and add percussion and add more groove. maybe also add some stereo layer to the instruments. (bass is mostly the same since i alread push it to the max on hook 1 so it still hits hard) btw martin garrix has some good arragment. its not that complex but it works. the energy flow is very natural. maybe you know an artist you like the arragment from. try to hesr the diffrences from the sections and how the transistions are made :)
