hiii hii I'm no professional but i do have some things to say ^~^
first off this piece is really cute and colourful, the side view is not bad, but one thing to be mindful of is how the body bends, the front arm is bent in a seemingly uncomfortable way, but the arm position you're going for is totally valid as long as you position it right cx also if you don't like how anime it looks then try striving for different styles of facial features (eyes and mouth make a big difference in those styles for sure) also backgrounds are definitely hard but that just takes practice. (but shading for backgrounds really makes it come to life!)
besides that, your art is really really good, and very cute! keeping working at what you love of course!
