One Line Drawing: Beautiful Smile

One day, a lady contacted me and requested to do a portrait of her teacher as a gift for her retirement.  After that, she changed her mind and wanted to have her own portrait and place it on her desk. Then she selected a nice picture with a big smiley face and sent it to me. At the end, I completed this drawing quickly since her happy face fueled me with positive energy.  

I believe that if we spend time exploring beautiful things in our daily life, positive energy can be increased.
