Yes, they are made-up. I'd like to say they were derived from Phineas and Ferb, but I'm not so sure. Ana is crying because people around her bully her, saying that her father left their family, when in reality he died...or something like that. The boy here, Sparky (his nickname, his real name is Xerxes....I think)is the light in the family. He's always trying to find ways to cheer up everyone around him.
._. ok, sorry, but first thing i thought after seeing this picture was " omg! a little kid is playing with a creepy ghost!" probably because his colors are so bright while she's just in gray. sorry for the misinterpretation.
although, now that i know what it's really about, i do find it pretty cute
Adorable! Initially when I saw this without the description, I thought it was something darker for some reason because of Ana's position and grayscale-esque coloration, but now I get it. Very good work
