Actually i think it is good that he used that one custom texture, since it will be hard to make like the eyes Pokémon-like without one, and since it is used for all of the Pkmn (which will be alot) it's k <(^^,)>
Now about the model: Great job on keeping the size low! The animations totaly fit the beedril and i like how you not only used his drills but also his 'tail' thingy (dunno how to call it! >.<)
