Entry #2, font logo should be bigger then tooth art, try to incorporate color orange into the design, how about putting a smiley line under the ii in "hapii"
#3, word dental needs to stand out more how about unbold hapii and change it to blue, bold dental and change to orange along with changing the tooth to orange
entry #24, make "dental" bold and bigger than "hapii" , make the eye of the tooth similar to design rank #1, just a smiley line............make "hapii" orange and the tooth outline and "dental" blue
entry #56, how about we change the smile line beneath dental to orange? Also play around with different fonts, I want to see how it look, you can also rotate the blue and orange around and give more variation of entry #56 to see if one will look better, so far, it's looking great
