Feebdack has been positive for #20. Comments were that they like the softer nature of the logo but not the 2 circles. Can you maybe remove the circles and incorporate the 2 "F"s as per #19 but in the softer font? Reverse out the colours and maybe also soften the font in the wording on the right? We like the less corporate look though.
However the contest is already in judging mode which means that only the 1st ranked designer will be able to submit entries. So you will have to temporarily rank me first to enable me to upload the new versions.
