The head wings on dragonair made sense because dragonair was already majestic therefore the wings were made to be complementary to the majestic look plus winged snake is a pretty coherent design

dragonite is a fatass dragon tales looking faggot therefore the majestic wings don't fit at all especially because it's not a snake anymore therefore the head wings just clash very badly and look mismatched since dragonite already had those on the back
the overly large tail is also terrible it doesn't look like it's a natural part of the body anymore
mega dragonite looks unbalanced as fuck it's trying to be "Majestic" while still looking like a fatass and it fails
