The order of your comic confuses me. It took me three read-throughs to figure out that it went:
Top right -> Left -> Middle Right -> Bottom Right.
Additionally, the grammar is... not very good, to say the least. Piccolo says:
"I did it because he cant know what im going to tell you theres a new threat."
That's grammatically incorrect for a number of reasons. It SHOULD have read:
"I did it because he can't know what I'm going to tell you. There's a new threat."
And finally, the illogical plot device. Goku just had his son attacked to force him away, I doubt he'd react like that, unless he's the world's worst father. Which he isn't.
