All I could think for Boey's new book cover

This is all I could think for Boey's new book cover. I suggested him to draw himself and River sitting next to each other at the park but then again it doesn't seem to stay in line with the title itself. Yeah he was right enough about that.

Well, I am planning to draw a boy holding a balloon back then but I am not really good with drawing.

What I am trying to say here is, a balloon represents a memory by a young kid. And he is holding the balloon as  that's been his life about when he was small. The unforgotten childhood memories.

How do you think?
