may be you could try a few fruity colors somewhere in 1,2 and 3 to see how it looks, and different types of letter case too ok, aslo if you could add as the slogan below in small letters fresh, natural, organic close to you to see how it looks and fits ok,
by the way nice work with the leave in the letter may you could add some other shape of a fruit or two something that still keeps the minimalistic appearance ok,
