I have just Finished Charmander and therefore finished the original three. Bulbasaur was done a while back, i sent it for testbuilding, i don't know if he started it yet or not, it's up to him.
If wants, he can build charmander too, so he would have all three.
I'm pretty happy with how charmander turned out, i was hoping for worse.
imo (i don't actually know their heights off hand) i think just squirtle is a little too big compared to the other two and char and bulb do look a lil too short and thin respectively but it totally gives them a cuter look and kind of stylizes them. So in terms of scale i just think squirtle might need to be a bit smaller
