Strade: Machine oil, grease, blood (real bad if he's recently killed/tortured someone), cheap cologne, cigar smoke, cheap beer
Ren: Really nice shampoo and moisturizer scents like lavender or roses
Lawrence: Rot, mint (to cover up the rotting smell), grass, dirt, earthy tones, small whiffs of different flowers
Derek: When in the desert, like must and sweat; at home, like really nice colonge (like ones from Gucci idk)
Celia: Nice perfume scents (roses, vanilla, orange) with a hint of alcohol
Mason: Smells like the woods; trees, grass, earthy smells. Also kinda smells like smoked meat (dude definitely smokes his own hunted game)
Died of shame...
In fact, it didn't turn out what I wanted, but I didn't have the strength to somehow fix this work, so I left it in a light meme form.
