Hi,
Not sure on number 1 as it looks a little soft to me but that may be the processing.
Number 2 is really nice - the only thing for me that is a little distracting is that the wall is not upright, I guess it is the angle it is shot from but it looks like she is holding the wall up. Other than that i really like it, nice colours and processing.
Number three has a wonderfull draw to it with those big eyes but the lip is slightly distracting.
