For colors or words: 'Magic' should be purple (primary color), 'I.T.' should be green, and 'Cloud' either blue or black.
In all pictures, I do not like the 'smile' (please remove, as loses the professional look).
start with #96, with the blue color fill, instead color the word text of blue 'Cloud', green 'I.T.', and purple 'Magic'. Try one in all capitals and other with combination upper/lower case.
I like the stars in #96, but prefer the four point stars, instead of 5 point.
Pictures are either 2 color (purple/green) or 3 color (purple/green/blue). Blue is optional.
if possible, try an aluminum metalic cloud background, like Apple's iCloud logo
