creative exercise for the week

Last year I attended a photography conference with Richard and Amy from Red Leaf Studios - what an inspiring couple!  I didn't attend the conference again this year, but wanted to try out the creative exercises they assigned to attendees...

1.  show negative space
2.  negative space with foreground
3.  negative space with foreground interest
4.  using light creatively
5.  framing

They used pears as their inanimate objects - hmmmm...have I overdone pears or should I use them again?
