I really like these but the white clouds end up blending too much into white backgrounds. Can you close up the circles by extending the blue down the left hand side and connect it to the orange. Then take the orange and extend it up on the right hand side to attach to the blue on top. Hope that makes sense.
But please make the Ops (bold) and the phere (not bold) which is reverse of how it is done in that logo i sent you. Also please make sure the font is "leaning forward" and italicized showing a bit of speed or leaning in.
