Here are a couple of sketches I did on my iPad. I think I used the Procreate app. and a stylus. I sketched these quickly from photos I took. I kind of feel like it was cheating because I used layers over the photo to trace the lines of the sketch. However, this was a good activity to see how the lines reflect the picture. I enjoyed flipping back and forth from the picture to the drawing and comparing the two. It helped me with getting the proper sizes and perspectives in the drawings.
