Hi,
#71 is your best entry
Could you please:
*Make
#71 without the face (so with helmet & dots - perhaps a little bit more abstract)
--> I want to know if the logo could be used without the "character" face.
*Use the following blue color: #4289DE
*Try to make it more web 2.0 style
I will move duplicate/older revisions of the logo to the not interesting side and rank only the unique designs.
