Great Job!
I find it quite interesting and not too shabby. The music can be improved from the transition from the Lu Zhi Zhi training to Du Gu Du Gu training. I find it a bit abrupt. The drawing part of Du Gu Du Gu knocking at the tree I think can be improved. Other than that, I generally find everything quite smooth, especially the fighting scene. A great job for your first flash.
