R/S/E Raichu-looks overweight.
Dragonite (all games)-looks overweight, and the pose is off.
What's wrong with the pokemon being fat? If you recall, Pikachu started out as being really heavy (eg Basic Set 1 card art, gen 1 sprite). Is Snorlax the only one that's allowed to be fat because being fat is its "thing"?
Anyway, here's my opinions.
RSE dislikes:
Pikachu lost its belly patch, but somehow Raichu still has one.
Zubat's wings are way too small.
Muk and Grimer still look like the exact same pokemon.
Ghastly looks way too solid to be a gas.
Mr. Mime is no longer fat.
Jynx is purple.
Eevee's ears are all wrong.
Dratini is missing the scaling on its belly.
Mewtwo just doesn't look freakish enough.
Rapidash just doesn't look at all regal like it did in gen 1.
Gyarados isn't using the amazing Yellow sprite.
Nosepass's foot looks like a mouth.
Torkoal is exhaling smoke from its nose... did it just take a huge drag off a cig?
Milotic is absolutely not attractive looking. Why does its dex entry say that it is?
Metang: why would you do this, gamefreak? Who allowed this abomination to live?
Regice doesn't make any sense. How do its arms attach? They end in a point, but the sprite tries to pretend like they actually have some kind of volume conducive to a ball-and-socket joint. No.
RSE likes:
Geodude looks way better than in gen 1-- no more weird "hairdo". The backsprite still looks just as silly, though, with that mop of hair ever present.
Wigglytuff looks actually 3D, which is great.
Moltres doesn't look like it's made of play-doh.
Fearow doesn't look like all its feathers are about to fall out.
Golbat didn't accidentally inject anaesthetic into its tongue.
Surskit is just so adorable!
Camerupt's absent-minded look is everything I wanted and more from the gen 3 version of Piloswine.
Spoink is just so adorable!
Cradily is mesmerising. Just start at it for a few minutes. How does it even work? Why are there circles, and more circles? Are they teeth? Eyes? Polka-dots? This is what I wonder when I lay awake at night.
Shuppet's eyes are half-blue, half-yellow, and form a green pupil where the colours intersect. What a great detail!
