A lot of people have been asking what tools I use to draw. I draw mostly these days on my Samsung Note 3. I use a program called Autodesk Sketchbook Pro for Android. If you visit that link, and it says it's missing, you're screwed. The thing of it is, the version of Sketchbook I use is no longer available for purchase, and more's the pity, because I don't like the new version.
The old version (which can be found around the internet, by searching for sketchbook pro apk) had the ability to lock the tool and swatch palettes to the side of the phone. For the life of me, I can not find this functionality in the new version. This is a hard line selling point, and the whole reason I use that software versus other similar competing products like Photoshop Touch (which has fucking awful pressure sensitivity) and Corel Painter (which actually has some awesome pens, but not separate erasers).
So when I tell people I use Autodesk Sketchbook, technically I'm telling them I use a product which doesn't even exist anymore, which is a real shame, because I use it daily now.
2015 is shaping up to be a great year. My plan is to make a portrait sketch every weekday, and a painted portrait every weekend. It's an ambitious goal, and one that will rely on the timing of others, so here's hoping.
