Hi! Thank you so much for the kind words! I use a 0.5 mechanical pencil for doing tighter outlines. I buy either Rotring or DONG-A lead. I think these are the 2 most common pencil lead brands available in Bookstores/Supplies stores here. For pencil rendering, I switch between 2b or 5b Staedtler or Faber Castel. I’m not greatly familiar with graphite mediums so I’m not sure how apparent the difference is between pencil brands. That’s about it. Thanks! :)
