In 3 days i'll be on a plane heading to Columbia to build schools for orphan children,
I was asked to paint a mural on a finished wall in the school... i'm really confused on what i should paint...

I was hoping, if you read this, you could help me out and suggest some ideas??
i have limited paint to work with, so i'm thinking along the lines of a smiling child holding a butterfly that is the colours of the Columbian flag (yellow, blue, red), and maybe a wash of colour as the background.
i would appreciate it sooooo much if anyone can suggest something!

thanks
