Dead-on focus. I can see why you couldn't look away. Great catch. Do you suppose she might've looked just as intriguing a little bit more to the right of the frame? ;-)
I don't agree with the other guy. I like how she is placed in the pic. It gives the idea more so that she is looking at something you can't see, that she is unaware of you even watching, that chance provided a look into the thoughts of another person. I like the feel of it. Keep it up!
P.S. If you get a chance, take a look at my gallery. Any comments, criticisms, advice, etc. on any specific pics would be greatly appreciated! Have an awesome day!
