This is very cute. c: I like the color palette. One of the things you could improve on, though, is anatomy. Even for cartoon style, knowing about anatomy is important. The arms look very short and the neck is a bit wide compared to the body. (This guide is very helpful: [link]) The legs are a bit shapeless also, but for more "chibi" styles this can look okay. I see that you shaded a little bit around the skirt, which is a start, but maybe you could try learning more about lighting and shading to add some more life to your art. You don't have to change anything about this drawing, I'm just giving you tips for the future. Overall, cute drawing. Keep up the good work!
I definitely like where you are going with this in terms of originality. Your art skill needs a little bit of work, though. The problem I have noticed is that the arms are waayyyy too short and it looks to me as if she doesn't have any elbow joints whatsoever. Her body looks completely stiff and her clothing is missing detail. Also, Her neck is completely out of proportion due to it being too large. Making several errors in your artwork does not mean that you are terrible at it, but it gives you great potential of improving and becoming a better artist. You can do it and don't give up!
