Last year, my wife bought me a Nintendo DS with the hopes of using it as a digital sketch book. It's been sitting in the box since December, but I finally got all the necessary software and got it running last week.
Here are my first feeble attempts to paint on the thing. I have one thing to say...it ain't a Cintiq! The 2" screen, two brush choices (soft-round & hard-round), no undo function, and no selection tools are a long way from Photoshop CS3. But stripping all the bells and whistles away from the digital painting experience is quite humbling and darn good practice.
I'm going on a trip to Italy with my family soon and I'm taking it with me. Hopefully I'll have a few sketches to post when I get back. (And hopefully they'll be better than these!)
