I really love seeing your art! It's very colorful and cute, and I love all the fun expressions you put on your characters! The poses, the facial expressions- also those hands! Amazing! The shading is flawless!
I haven't ever seen a background in your art, so if you aren't very good at them, I would definitely suggest drawing your room whether in a sketchbook or other, or maybe drawing a garden or some historical place.
I also see that you seem to have a little bit of trouble with the facial structure. You are obviously very good at anatomy and drawing the face itself, but I think the jaw is usually off a little, and on one or two of your reslistic drawings, the eyes seemed a little too close to the middle of the face I think. All in all, you don't have a lot you need to work on, and the two things that are slightly more noticeable in your art are very common problems. Hope this helped!
