skin and face is nice but i wouldn't do that super short hair... mesmers are so elegant and feminine - i wouldn't want to make her tomboyish. My mesmer used to have the blonde hair with the flower in it but I changed it ~ I think the darker hair looks better (it's stronger contrast, makes features pop). And I think the first two hairstyles look nicer - just looks more balanced with her features for some reason
Here's my mes so you can see what I did... of the ones you have shown I would do one of the first two, though I still like the hair I picked the best :P Either way she would be cute!
