I'm very much a traditional artist but I've had a lot of fun playing with an iPad app called Procreate. Using a Wacom Stylus (I've also used the Pogo Connect) I have pressure sensitivity on the iPad and this app totally gets out of the way and allows me to have fun drawing and painting digitally. For me right now it's just a fun diversion, but I highly recommend Procreate if you're thinking of painting or drawing on the iPad.
There are some serious digital painters out there doing some incredible work: Jon Foster, Craig Mullins, Justin Sweet, El Coro, etc. immediately come to mind. I love their work, so please understand that I'm not making any kind of a judgement about digital being less than or anything like that. I myself am more wrapped up in traditional for all kinds of reasons. But that's me. I do love what I'm getting out of Procreate and will certainly be exploring it more and more. But my heart is still with oils, etc.
I approach these pretty much the same way I paint traditionally, give or take.
I recently did a workshop on using Procreate in the August 2014 issue of Imagine FX Magazine that included a digital demonstration. In it I go into detail about how I make my own brushes in Procreate and how I attack one of these head paintings. If there's any interest in my uploading some of my digital brushes let me know.
Here is a link to my SmugMug page with a few of the videos that Procreate exports of pieces:

Hope you like these pieces. They were a lot of fun to do.
