I find the entry #4 quite interesting (the amalgamation of the A and the W). Here are some suggestions: - Use the shade of blue and grey similar to entry #2 - Use a font more "Calibri-like" for the title - Style the logo with less sharp angles (sorry it quite hard to be descriptive...)
Thank you for your efforts, this is much more what we had in mind. We are in the process of reviewing (3 people are), and will let you know about our decision tomorrow.
