I wasn't feeling the love with my limes at first until I added the cobalt turquoise.  Then I messed it up with too much blue in the shadow. I prefer to draw with pen but no pens were used to make my limes, just a brush with yellow paint!  Still wasn't happy until I added some text of a fun "summer time" song to chase away the winter whites that is the landscape here.

Koi watercolour and Winsor Newton cobalt turquoise in my Moleskine.
