thanks for the comment!
funny enough, i did have a bassline written for the song. it sounds okay when i was composing it in mobile, but when i tried to mix it on pc, it sounded so bland and distracting to the general composition thus i opted to discard it. unfortunately, due to time constraints, i wasnt about to write a new bassline, so i just kinda salvaged the lower frequencies of the synth pads and mixed it as the central bass. there's some "oomph" but still lacking in "growls" if that makes sense. when i polish this track further after the event, i'll try to cook up a new bassline
as for the thin, i may realize why that is. usually i like to do mid/side eq on the center pan by making the instrumental quieter only on the center so there's space for the vocals to clearly be heard. however, i failed to realize in time that, since my song is mostly synth holds with minimal vocals, this meant scooping the center resulted in most of the song having thin center. this is something i have to consider when polishing the track further.
once again, i appreciate your input!
