Sometimes it is necessary to use whatever tools you have available for sketching. These sketches are done in HB pencil on notebook paper. Sorry for the poor quality of the scan. I don't have photoshop; I have Corel Painter X. Though, I don't really know how to use it. I tried to make the sketches darker so you could see them, but as you can see, the quality is not good. I was practicing freehand circles while watching tv.
