what might help is using channels to cut out hair, it can help in time, especially when theres a good contrast between hair background... initially didn't think there was anything changed and then after picked up on it..
Top arm is a lil blurry and the most obvious was the scale of the grass, but then again you might get grass that big in the US Also the perspective is a lil off, like were really looking up at you, but the grass is almost level looking at the edge of the field in the background. Youre getting better thou!
Hmm....I love it. I love those type of Backgrounds. They are very exquisite. The sky with clouds are rather nice and great. The field looks very country side, of which I love country side photos a lot. And you fit very well in this country side photo
getting good your edges are smoothe except forthe arm shere its a little over feathered. lighting matches pretty good your proportion and angle is a little off.... but i cant critique you because you are awesome <3 LC <3
