I drew this yesterday on the way to Riverhead Raceway.
In the car. -.-
...I can't draw feet.
So this ended up being a practice in.... Rounded shells.
Or rounded things with a pattern.
Or something.
The character in the corner should mean "Turtle". Hence the "Ka'me" title. I hope I wrote it correctly- it was hard to read the kanji in the tiny text dictionary while dad was driving on a bumpy road.
