Glad to see you post some art Lunar
First I will say that I love the orange and yellow polka dots! It took me quite a while to learn how to deviate from my 'chibi' style, and it was rough getting harsh crits on my human figures, but from that iv'e learned a lot, and the chibi style teaches you a lot more than you realize!
Youve got the basic idea <3 In my opinion the head on your drawing is extremly too big, even for a chibi, unless you intended it to be.
I hope you don't mind, i saved your image and played around with it myself, heres what I got from your image on the left, and mine overlapping your origional on the right
Seeing those overlapp you can see that he head is a tad too wide. Hands and feet are hard to learn, but once you do they make an image look so much better~! I can draw up how i draw my hands for you if you like, or DA has plenty of tutorial on them <3 The eyes look a little awkward the way they are drawn as well, the top line comes out too far around the actual eye (eyelashes?) and doesn't meet up with the bottom.
I hope this helps you out ~ If you need any more advice or criticism I would be happy to help you out further
