I really like this concept...I woul dlike to look at the Font though...The "k" looks too much like an "R"...what if we brought two curled lines down around each side of "Inverted Networks" to incorporate the "plugging into the cloud" theme?
This one really jumped out and grabbed me...lets keep working this angle!
another thought would be to put a gradient on the text so it appears to be going "up" to the cloud? just an idea to work with.
also...I am a big fan of all caps...tall and small, but all caps...see if you can find a font that will accomplish that!
actually make all the colored areas a mixture of the exact google colors...blue, red, green, yellow...
I like the boldness still, but the inner lines (inside the could)...lets try to make them thinner to give the cloud some "definition"...know what I mean?
another thought I had would be to split the Inverted and Networks a little further and create a "plug" going up from the slogan to the cloud...does that make sense?
