It's a cute picture, the tilt works here, but the fill flash is too "hot". The fill exposure here dominates the ambient on the child. When using fill outside, you ideally want to balance out ambient with flash exposures so that it really does not look like you used any fill at all (if that makes any sense). Foreground and background exposures should be matched as much as possible. Ideally, the flash should not contribute any more than about 20-25% to the total exposure in most situations.
