I have over 130 sketches done on my iPad and iPhone that I have on my blog or saved. I have never tried to do a very detailed drawing. It takes longer to use the electronic tools. It would be too much like colored pencil and boring with all the undos and changing tools. With a pastel or pen I can just change the pressure or direction of the stroke and get on with it!

As you can see, I finished this morning and grew bored of the whole thing and just quit. Sigh.
I walked yesterday around the lake. It is quite pretty.
