Solution:
Illustrated a whimsical, simplistic fish with a half smile-half frown expression. Used blue and yellow colors to represent a "blue" mood and a "sunshine" mood. The logo symbol when faced on either side alternates expression from smile to frown. The letterhead uses the logotype version to reduce the emphasis on branding. It also appears at the right so not to promote the practice foremost instead the letter's salutary greeting is the focus when read from left to right. The business card true, to its function, is much aggresive towards branding the practice. Yet it is designed to be evoke warmth and comfort.
