Was only able to watch up to Wigglytuff, as I gotta get goin', but her Pidgey was just the best thing ever. I'd take that design over what we have now. ;P Also, her Rattata and Raticate were just the cutest thing ever, and I also felt the same way about Clefairy and Clefable. Jigglypuff just reminded me more of a older iteration of Kirby, and Ninetales made me lol.
I just knew she was gonna screw up once she hit Nidoran (and I say screw up lightly, guys). Most people don't know how to draw Nidos from memory, so I'm not surprised. I can do all but Nidoking without needing a reference myself. As for the rest, and speaking for the topic itself, I think I'd generally fare a bit better except for all the hardcore Pokemon. Like, I can't draw Gyarados or Kabutops. Scyther, Mewtwo and Aerodactyl might be a stretch. I have a general idea how Kangaskhan looks...
Nevertheless, I can guarantee you all the first generation. My memory is too fuzzy to remember all the numbers in gens 2 and 3. :\
