I don't even know her to begin with so every photo would be lesser known to me at most ^^ - completely unknown the more appropraite description.
Looking very good though, not a whole lot one could do wrong with proportions if you paint from from a photograph. The shading and contrast is very nice and I'm absolutely stunned by the hair. Hair is so hard. So very hard. I can't even begin to put into words how I can not draw hair. I'm better at human proportions and I'm terrible at drawing those (even though I know what they should look like...). So yeah - full points for hair and no distractions XD
