#1 and #2 are underexposed. #1s subject may have been more interesting if you followed the rule of thirds on this one. #2 has some good bokeh going on, but again, it is very underexposed so I'm not really sure what it is that I'm looking at. You may want to bump your ISO numbers next time and move from there.
3 is SOOC. 1 has had a green colour boost, and 2 (I don't know why I did it) but I increased the contrast and lowered the exposer. Now that I look at it on a better monitor I see that it shouldn't have been edited. The original isn't underexposed, I'll post it later.
