Overall i enjoyed your clip there were no big mistakes it flowed really well and it was pretty clean.
But your camera movements need work, they are too rough like at 0:39 and also the FMA leaf transition is sooo overused XD that i'm already sick of seeing it but that's just me. Also the mask at 1:58 don't be lazy and chroma key
just mask, masking is fun
And the part at 2:06 try to avoid changing motion roughly like that, what i mean by that is that the motion goes inwards at first but then there's an outward zoom it really kills the motion you should have continued the inward motion or just transitioned to the other scene.
Well i liked it good luck on your next project O/
