Natalia

The rail she is sitting on is a strong lead-in line.  The rail to her left is a more subtle lead-in line as it blurs into the background and points to her face.  The pose is okay but I would like to see her left arm relaxed a bit so as not to be so straight.  The brightness of her legs balance with the bright background area top left.  Her face balances with the blurred square (locomotive?) above her head and to the right.  Nice composition, good use of space, and good color and exposure.  I like her confident expression.  Nice job.
