Sure we always got somethin' to say

Shot 1- Not crazy about this pose. the model looks stiff here, a 45 degree angle would have looked better imo
Shot2 - an interesting pose, sexy. The eyes could be just a bit brighter and sharper (they are quite good already though)
shot3 - My fave of the lot. Model looks great. eye brightness quite good, eye sharpness very good.
Shot 4 - has a very sexy feel to it. Model looks good eyes are sharp (though the model's left eye looks like it has an eyelash/dust in it) maybe the cropping at left is a bit tight.

Hope that helps - Marko
