In that case I would recommend using another color instead of white :)

Im using mspaint for pixelart, So I can't add transparency to the background :) thank you for the comment!

I also thought something unnatural, but I can't find detailed reason about it before you noticed it me. Thank you for the feedback!  I forget about colouring her feet ^^ next time I'm going to fix that thank you!

Great colours and contrast! However, the anatomy seems a little off around the hips, and how her right leg attaches. Also, the whole sprite is rendered beautifully, except the feet, which are simply one flat colour. Is this deliberate, or did you forget?

You could add transparency to the background, it will look better in your gallery :)
