Hi, Ismael! Great to see you over on the Tumblr side of things. Currently my favorite tool of the trade is my Cintiq it’s such a pleasure to draw on and has a really natural feel to it. My current digital set up is a Wacom Cintiq 22HD hooked up to a 2009 MacBook Pro. My favorite tool of the trade on the traditional side of things is my Kuretake brush pen. It provides a really nice, varied line width. I will usually draw in a blue Col-Erase, clean it up with a lead holder with a harder lead and then ink on top with the Kuretake.
