I'm in favor of pink shiny Meowth, as it matches the real shiny.
I'm not much of a spriter, but Parasect could use a different pose. It looks like it's doing arm stretches or something.

I think flexing the elbows could make the pose much more moe and less awkward.
That said, you're all doing a great job, and I'm looking forward to future updates :)
