i’m curious then, what characters have a strong scent to you? ….what does Garrus smell like to you?

This far the strongest character, mostly by the presence, has been Dragunov. It took me about six months daily basis studies like going through pictures, doodling, watching videos, playing and looking how other fanartists had drawn him before I was able to make my first proper picture of Dragunov. Now he’s easier to draw but still he gives me hard time with digital medium. Dragunov is easiest to draw with traditional style. 
Though he has strong presence for me, his scent is what I call “moderate”. Maybe I’ve just gotten used to it? I’d say his scent is “murky soft”, maybe a bit “spicy” without being spicy. There’s hint of something “light” in the scent, too, maybe because he’s too young to smell like an old, spicy man? Maybe leather would go pretty close to Dragunov? I really can’t describe it better than this. 

The absolutely strongest character by scent is Renji (from Bleach). He basically “reeks” like pine.

Garrus is a new character for me so I’m still getting used to him. He has also a strong presence and strong scent, yet he’s kind enough to “stay still” while inspecting him, while Dragunov felt more restless (I don’t know how to hell that makes sense, but that’s how it feels xD). This means I probably don’t need to spend six months beforehand but some weeks perhaps until I can draw him right. 
Garrus’s scent is very earthy and a bit acid. A moist soil would perhaps be the word I’m after, though I still have to spend more time with him to get the scent right. 

Fenris (from Dragon Age 2) has also very strong, manly yet nicely alluring scent. It took a while for me to get used to him. He settled down soon after and was “willing to” bend into animations, which helped me a lot to get used to his scent and presence. His scent goes very well with Givenchy’s perfume Fi.

I haven’t found any other perfumes for characters (except for Fenris and Balthier) but I’ll let you know when I come across perfumes like Dragunov or Garrus :3
