I love Renoir's paintings of 'Girls by the Sea'. In my sketch I wanted to see if there was a difference between drawing with a regular #2 pencil and graphite drawing pencils ranging from 2b to f. Of course there's a difference! I wouldn't have nowhere to spend my measly few pennies if there wasn't! The graphite drawing pencil 'smooths' onto the paper like butter compared to a regular pencil. Not that the regular #2 pencil doesn't have it's place. I would use it right along with the drawing pencils - maybe to fill in the hair or non-essential places.
