Rococo teatime

Hello,
  When I came upon your art I literally gasped with joy.  I have searched far and wide for the perfect Marie Antoinette.
My passion is cakes and I've named my little business Lady A Cakes.  A for Antoinette!  Your Marie would make my business cards perfect!
Is this allowed.....to use your artwork in this manner?
Please let know as soon as possible as I am extremely excited about this! Thanks so much, Pam : )
