I couldnt find the reference but Ill just give feedback on what I undertand, first I think how you rendered some parts make your drawing look flatter. what I will recommend is to practice form wraping and shading like the example I drew. secondly I will recommend you to practice manichins before you go into a detailed drawing (like break it down into simpler shapes before you go into anatomy folds and details), not even saying to do an undersketch just break the reference down. theardly, will reommend to study form manipulations like taking basic forms and streching them or twisting them or combining them, really helped me understand form alot better. hope this helps btw kim jung gi is my idol too. | Artwod Feedback
