entry #1 on the right track, like the incorporation of a briefcase to bring the professional look. The up-stroke of the K also points towards the future career. I would prefer the use of lowercase letters as opposed to all caps. The tagline should also not be all capitals.
The basic logo is sound but in this last round of the comp If you could please provide some variations and maybe "bring it off the page" a little to give it some depth
I still like #86 but it is currently my third choice due to the other entries having a person in a joyful pose representing hope for their future career. your attempts at doing this are a bit off the mark as they are not warm enough and a bit robotic in nature. see what you can do much thanks :-)
