your art is really cute n' pleasing to look at! what program do you use to draw / what brushes do you like using?
That depends! The last two pieces I posted were drawn "traditionally" with black ink and a G-nib. I used to do most of my digital art in CSP, which I loved, but now that I daily drive Linux Mint, I'm trying to get used to Krita, which I'm told is very powerful. When I just need to do some color adjustment, I'll use GIMP.
Between digital and traditional, I enjoy the tactile response of traditional media for line work, but I do lots of canvas flipping and resizing sketches to fix composition and proportion.
Given my druthers and infinite time, I would probably sketch with pencil, scan the drawing and fix the pose digitally, print the sketch and use a light box to ink it with a nib, then color digitally. But that takes a lot of time, and the think I'm working on most right now is efficiency!
