HEAD LINE: Mum Leah was "nervous and stressed', son Harry was 'excited and chilled' as they arrived in Zone One in Greville Smyth Park for the start of the mega paintathon. The finished work which took 20 hours to complete over the long weekend is called What’s In My Head. At the end Harry was exhausted. Leah added: "It was hard work keeping him on task and focused especially as his school friends kept coming to see him and both his teachers from Nailsea School." Leah took all the brilliant photos. The first slideshow is all about Harry and the second is other artists and Upfest visitors
