they're all good pictures.. there's nothing wrong with the composition-- each shot is obviously what you were going for, so therefore i don't believe in any artistic critique.


from a purely technical perspective, however.. you ought to consider a slightly higher exposure. the second picture in particular would lose a lot of detail in printed form.. there's nothing wrong with giving yourself a little extra headroom, especially as you can tweak it in post. that was a lesson i learned the hard way.
