A more constructive criticism as well as some tips.

• You should try to extrude then sculpt the ear from the side of the head rather than rely on a new polygon, it looks awkward like a flesh colored hair accessory.

• The "hair" polygon your using is a bit messy, you should start by molding a cube around the characters head then creating more edge loops and adjusting each vertex point until it looks like it covers the head in an appropriate fashion, lastly you should export the UV map and push it into photoshop (or whatever graphic design tool you use) and start with a simple hairstyle but only using 3 colors, a transparent, an outline of the hair and a hair color. From that point you should slowly add detail until it fits what you are aiming for.

• Lastly the face which looks pretty good already just has a few issues with the eyes, nose, and chin in my opinion. Try pushing the chin up slightly since it looks like its too long(if that makes sense. For the nose you should try pinching the end of it and dropping the width since youre aiming for a feminine character it doesnt neet to be so broad. lastly her eyes, or I should say her brow. I know more feminine designs have very subtle brows but she seems to have none, its like her face just rolls off to the top of her head. This can be somewhat helped by pushing the bridge of the nose slightly further in.

I hope this helps.

Everything is good except for texture quality and obviously the ears (unless you meant to make the ears look like that) Would love to see a whole body shot of the model.
