I tried to look up DA and tumblr but couldn't find anything so I'm sorry if I missed it and you have been asked about this before - what tools you use for drawing? I love how your sketches and traditional work looks (I'm such a nerd for sketch-type art).
I have a public, free resource page posted on my patreon. On it are listed a number of my brushes and presets that i use for drawing. It might help you out!
