I'd also argue that the watergun motif for Intellion makes it's hands one of the key elements of it's design which, as any artist will tell you, is one of the hardest things to draw.
It's also less about drawing the pokemon 1:1, a good design is recognizable even when drawn like pick related, which I would argue mons like intellion, talonflame, eternatus, and a few others are not.
