i'm not very experienced with chibi/extreme proportions so i tried my best to read what you were going for with the original, hope this helps! there's nothing wrong with extreme proportions, but it can make it hard to viewers to read poses or expressions if some facial features are too small/crammed or if the body silhouette is too round & blobby there are a lot of different ways to go for a cutesy/chibi/exaggerated style of proportions so def play around, this isnt the only way at all to do it :]
