If you wanted to make some sort of aliens then mission accomplished.
But if you wanted to make humans, you definitely need to practice. The noses, the eyes, the hair. basicly anything looks of. The only thing you did okay was the title. But the gradient shading just looks awful, and it always have. But it seems like you use it in everything (hints, the eyes). Not just this artwork here. But also your other art, and your animations.
The only advice i can give you, is to try something new. Not just recycle this anime ish art style.
Learn anatomy, learn about colors, learn about perspectives. Just do SOMETHING.
For all of those years you have been drawing and animating, it's just not possible for someone like Oney, or Ricepirate, to be 1000 times better at stuff like this, then you are. Get your ass in gear and just practice man!
