Angry Birds Seasons Mooncake Festival Level 1-11 Walkthrough - AngryBirdsNest.com

Basically used annach two bird strategy but obtained a one-bird solution with the tip from @bonneypattycat.

Played this level for a few days at 124k+ with using two birds (need 85+ to the 90k+ after the first bird), but kept trying for the one-bird solution and finally made it.

Aiming tip: zoom out and line up the launch basket about in the middle (maybe a tad lower) of the dark purple horizontal strip in the background and activate immediately upon launch. The top BB destroys the upper most flower, bounces on the top horizontal glass plank and only takes out the fourth left block from the bottom on the right structure. Only taking out that fourth block enables the entire right structure to fall by a prying action of the wood planks to destroy both right pigs, most of the time. The bottom pig takes out the lowest and largest vertical glass block on the left side whereby causing damage to the structure so when the stones from the tnt blast hit, hopefully, the entire structure will fall. The luck factor comes into play with the tnt blast. On at least 6 occasions, the left most pig remained. This level was fun and finally obtained an above average score and gained 11k+ in the process.
