>>41743525> Blastoisefucked up the Cannon and claws making them look unnaturally small, also head is relatively smaller to overall shell, look at the sprite and you can see the head's hole creates a thin ridge around the back of the neck that connects to the arm ridge, in contrast on the 3D model this is all one seamless shape.
> TyphlosionLoss of flames
> GengarLoss of expression in idle
> Skarmorythe sprite presented isn't particularly good either Skarmory's just a generally janky looking Pokemon, however making it always flying was a stupid choice
> GyaradosAs other anons have pointed out this isn't even the best sprite of Gyarados (RB, Y, Gold, FRLG & HGSS sprites are better), regardless it's just the neutral stance of the 3D Model, it should coil itself.
> NidokingHonestly one of the less egregious ones, arms should be larger as should legs relative to the body, most Pokemon suffer from losing the battle readiness of their sprites.
> ScizorHonestly compared to that sprite it's not really changed now if we're talking Gen III or HGSS sprites though then it's the loss of the battle stance
> TentacruelMakes it clear how many legs the Pokemon has, Sprites always made it seem like it had numerous legs, the mantle should be larger and rounder, in addition the reds should get distinctly darker towards the center, the beak should be more prominent it's meant to be as long as the mantle if not longer. Primary tentacles are also underdeveloped, look at the RS, DP, Pt and B2W2 sprites and you'll see the front two tentacles are supposed to be much thicker and longer in some cases than the other tentacles.
Overall there's also just the washed out colouration of all these Pokemon in 3D.
