The idea of an airplane is not that bad: it represents indeed something concrete, it gives a sense of power but it's difficult to consider viral. In general, I also would say that the way you have drawn the airplan is good, however I do not like the fact that the shape is rather similar to a Z and someone coud read "zottani" instead of "ottani". Think to something different, you have good skills as a drawer try with a different object !!
My suggestion is that you should work a little bit on the airplane trying to remove the impression of the character "Z". Also I like the idea of the entry 13, maybe to be more "viral" you should consider to add additional lines and balls starting from the existing ones like it was a synapsis. I don't like the flame.
