I honestly really love what you're doing here. You're making realisticly proportioned, beautiful sprites. But like Censen said, try to stick with the top view so more people can add these into their games (if they're private, then they'll flow better with older sprites) and these will really get attention.
Great job, but also remember to not make the smaller pokemon too small. Bulbasaur and Charmander are too small and look more like colored blobs. Maybe you can upsize everyone; make the 1st evolutions the size of the second, and so on.
Finally, Lapars is a completely different view from the others. It looks sloppy and inconsistent to me. Try to keep the same view for all the sprites so they flow much better.
I love the color choices, very soft and natural. Can't wait to see more!
