It's called "Art Academy - First Semester" and it's just what it sounds like. It's a step by step of the basics with a little bearded cartoon guy that looks like Grumpy of the seven dwarves and his name is "Leonardo" - of course! He has a black and white puppy dog that pops on screen during loading and lesson introduction times, just like my dogs, so it connected with me on that level immediately.
Since I have never had art lessons except once in first grade and once in 6th grade, this is rather enlightening for me and gives some excellent tips on how to get shadows and shapes to look the way you want them. Below you can see my slowly improving technique with each lesson. The first two are pencil sketches obviously and then it moved into painting skills. I love the fact that the DSi lets you upload it to an SD card so you can save it or show it like this. It's surprisingly accurate for being a touch screen, and a whooole lot cheaper than buying art supplies.
I Really labored over this lime half. :P
