My husband and I went to Reid State Park yesterday. We like to sit on the rocks and watch the water and birds and people. I took my sketchbook along and did 3 pictures using a ball point pen. I started with a micron pen but it was so windy the ink dried up before it hit the page.
#3 is the first time I stuck a person in a picture. This guy held still long enough for me to sketch him in quickly.
Real rocks are more difficult to draw than imaginary rocks.
