This is a sequel picture my earlier drawing of Jake and Rose. It's also an "American Dragon: Jake Long" version of the Danny Phantom Family Portrait done by [link]
As you can seen, it's Jake and Rose with their young son Jake Long Junior (remember the episode "Bite Father, Bite Son").
Since it was never confirmed who Jake Junior's mother was, i went for the obvious choice (I mean come on, who else could it be). As far as his personality goes, i'd imagine him as being just as fun loving as his father, but also rather mature and serious for his age (a trait he, of course, inherited from his mother).
I did imagine him with dragon powers and even did another version of this picture where he had red, reptilian eyes. But i decided to go with this one instead.
