#1 I like the splash of color! What I would like to see is the woman "lynx" sexier and an more curvaceous. I also would like the word lynx to be bolder.
#5 Love the lynx in #5. Would like to keep the font and size of mature in #1. I need the woman in #1 to be cleaned up a little,, I think if I could see legs or there be more definition to the bottom half. Like the mature sexiness in #1. Also keep the tail like it is in #1, where it looks like an extension to the "x."
Per your comments, the logo with combined concepts. .. I'm experimenting with different poses of the 'Lynx Woman" -- Ears can be removed if they seem a bit much. Also I added hair to the silhouette. That can also be removed if you preferred the 'sleek' look of the head in the original.
After seeing the last entry, I'm am definitely more partial to the first design. The lettering is perfect on the latest entry, however I don't like the ears and she seems to loom over the words. The original is the perfect if you could just make the lynx font like number the number 5 entry.
