tracing line

Those are some sketching I made. In this case, I show two different sketches, on the right side, I still put the sketch inside. That's for helping me to establish the line step by step. in the other case, you can see the left one, there is the tracing lines without sketch, so it looks clearly how to establish the line.
I made it using 'pen tool', for establishing the stright lines (inside the box for the date) I was using 'line segment tool' as my tool, and for creating the circle form (left-up) I used 'ellipse tool'
