I would say, yes, the sky was blown out. I wouldn't say that's a complete problem though. The overall scene, however, is a little on the bright side. Of course your subject is properly exposed but everything else is a little over exposed. Judging from the shadow it appears you were shooting into the sun. If possible I would shoot from the other direction so you have the sun behind you.
lovely use of tilt... and great idea.. that boosts my vote on this image by 3
blowout sky and overexposure... that brings down the vote by 3 - so I give a 6... with better quality the idea and execution would have gotten a 9...
