I like this. Good job!

Thanks for the feedback! I did actually think about adding additional frames to the walk cycle, but my friend is making the game mostly by herself, and more frames adds a significant art burden over a large number of sprites. In this case, ease of creation is more important than it looking as good as it can, I think.

Moving the legs closer together is an interesting idea. I'll give it a shot and run it by her.

Using the standing sprite as the middle frame makes it really tough to make a good walking animation, but if you move the feet in the standing sprite a little closer, it should work better, while still working as a standing sprite (albeit a less confident-looking one).

There are also scripts out there to allow using completely separate walking animations. If you and your friend are interested in making the game look its best, I recommend looking into those. The three-frame walk cycle with the standing sprite as frame 2 works nicely for the games with 16px sprites that initially inspired RPG Maker, but they don't work well at this size.
