I've used my new Kobo for more drawings. I used my ipod touch to look at reference photos on RedditGetsDrawn and then sketch them on the Kobo. No color and such for the Kobo but at least this is a portable way to get the line layer done in my drawings.

My plan for these is to take them into GIMP and work on them further - adding in grayscale and color
