Bulbasaur family from Grass-Poison to Water-Ground
Charmander family from Fire (Fire-Flying) to Grass (Grass-Fighting)
Squirtle family from Water to Fire
Mew and Mewtwo Psychic to Ghost
Was going with the rule of going with one of the types their original is stronger over but I really wanted to draw Mew and Mewtwo as ghost pokemon.
All for now, maybe more later.
