She is cute as a button. In the past I chose a complete avatar from Razzanova which I compared to the pictures you have in your albumn. They somewhat approximate your face, better than other prefab faces, and are sure to be less expensive than custom made. The main difference I notice is that your eyes are set somewhat higher in your face than these avatar's faces and the lips may be a bit fuller. You can tinker around on them a bit. However, I wouldn't do it without first making a copy of the original so you can go back to that. I've tinkered with some finished avatars and occasionally improved on them, and sometimes made a hash of them, so it's a toss up. You can find them under the "Avatar Components" category on the SL marketplace.
The thing is, in graphic pictures the eye is always more pleased with symetry. So that's what the finished avatars go for and why they look so good. Going for realism is good, but imo it doesn't always measure up to what we assume it will look like. Try taking a photo of yourself straight on with no hair over your forehead looking straight at the camera. Now draw a perfect five pointed star over your face. The top point of the star should meet the center of your forehead right where your hair line starts. The sides of the star stretch out to the temples and the bottom points come down past the corners of your mouth and end at either side of your chin. If your features fit perfectly along the lines of that star: the brows lining up with the horizontal line from temple to temple and the vertical lines from the top point meeting the outside of your brows while the crossing lines through the middle of the star touch each of the corners of your lips and intersect at the point of your nose and you still have a perfect star, then your face is symetrical and will be seen as beautiful by the human eye.
Otoh, if you draw a star to accomodate those points to your features and the star does not come out symetrical, the less symetrical it is the less attractive it will appear as a piece of graphic art, as in cartoon form. My dad was an artist and he used this method over and over to assess pictures of models and movie stars he painted portraits from. The closer the star he sketched on their face was to perfect the more beautiful they were considered to be. I guess my point is that using a prefab avatar isn't a bad way to get your look and save some money at the same time without making yourself look totally like someone else. At the saame time, you will still still resemble yourself, but won't appear oddly too realistic.
