Since mousing is a full-time reality for me, occasionally my hands hurt and it makes it difficult to draw. I thought I would try sketching with my iPad for a lighter impact. This basically feels like finger-painting, except it's not messy!
I find it awfully easy to get bogged down in unnecessary details, no matter what media I'm using. In many ways, I like the first iPad drawing I did, it's simple, direct, colorful (even though it's a bit "squashed"). See it here.
The app I'm using is called ArtStudio, it got 4-1/2 mice in 257 reviews, and cost under $10!
