These are pretty good, especially the mushroom! The only thing I recommend is the color palette. Earthbound uses a very distinct colors and rules on every sprite, the most important being black is never used for outlines, it uses a very dark brown. The game overall never uses flat colors.
I recommend looking at the Earthbound enemies sheet for reference:

Hope this helps!
