So first of all this is supposed to be only a short while after the games are over and Gi-hun goes to Sang-woo's apartment and here he's lying on Sang-woo's bed trying to call him but obviously it's just going to voicemail. Very sad, now some details: I put Sang-woo in his outfit that he died in, also you can see the wound where he stabbed himself in the throat. I'm not sure if I want this to be ghost Sang-woo or just Sang-woo from Gi-hun's imagination/memory but either way Sang-woo's face is clean and he's wearing his glasses cause (wether in Gi-hun's mind or as a ghost) this is a "better"/"more free" version of him. They both have wounds/scratches on their hands from the tug of war game, also the cut on Gi-hun's face from the glass bridge game is not as visible anymore because it has started to heal. I also wanted Gi-hun's nose and eyes to be red so that it looks like he has cried. Sang-woo is looking directly at Gi-hun, while Gi-hun is looking at his phone cause he obviously can't see Sang-woo. Also I tried really hard to make Sang-woo look like he's not really there and also kinda out of place but then also I wanted him to still fit into the whole drawing and not pull the visual focus away from Gi-hun too much. I hope that worked. I also used a slightly warmer colorpalette for Sang-woo and gave him brown outlines, while Gi-hun's are blue and he has a colder colorpalette, cause Sang-woo is supposed to be like this kinda warm glowy memory/ghost from a happier place. I think that's it, I hope anybody was interested enough in my art ideas to read this
