The eyes are spaced too far apart. Other than that, adorable, really. =3
Shaymin. . Looks traced and blown up. Also, the thumb on your chibi looks like an actual finger, rather than a thumb.
This is adorable.
That Pikachu also looks traced and blown up. That's the only thing I see wrong with it.
The Butterfree's head is oddly shaped and seems a little flat near the back. And its right antennae is a bit smudged.
Your chibi looks like he fell into a pot of ashes. XD
It's cute, but it's really hard to see the mouth.
Adorable.
This one I don't like at all, to be honest. The Seviper is way too small and looks flat by the bottom because of the way you drew it around the leg. And I don't like the rest because of personal preferences, so it's no biggie.
Adorable.
