This Loish made the classic mistake when mirroring eyes not correcting the reflecting light direction in one eye. Good that you corrected it in your version. There is a very bright light coming from the left side. remember that there should also be a contrasting shadow.

Also, you drew the shadow of her chin as if the light is coming from the top right when your light is coming from the left side.

The reflecting light on her nose is abit to long. If you look on the original the nose is not that large.
When drawing lips ( personal preference) Try not to make it a closed line.

Your lines are abit sketchy, try to make smooth lines. It takes allot of practise but will make it so much better.

Try useing both thick and thin lines, it addes allot to an illustration.

Keep it up!
