I'm no artist, but I think your art could improve drastically if,
You clean up your lines a bit. IE make them more uniform and less squiggly.
tighten up on your proportions. such as shrinking the head just a bit, making the legs more leg like, make the eyes more uniform, eyebrows that are thicker in the center, work on your hands( I know hands are hard keep trying.)
Make the blush more subtle, it'll look better.
Your art has gotten better, keep up the good work!
