Hi Diana,
No, you haven't, in fact I would say "not enough"
All would have benefitted from sharpening after downsizing.
#1 needs a bit of a straighten. perhaps even perspective correction, so the buildings are vertical and parallel to
both sides of the image.
#2
could be perspective corrected, but since it is roughly level, with both sides leaning in the same amount, it looks fine
#3 deperately needs some
Local Contrast Enhancement (LCE)
Here it is with LCE, downsized and sharpened (and with the litle bit of sky hidden).
#4 would also benefit from a white balance, some LCE and perspective correction/tilting.
#5 might benefit from some recovering of mid-shadow tones and personally, I'd have waited for the woman in the red coat to either leave the scene, or pose better for
your composition
That is an amazing sculpture in #5.
I hope you don't feel I have been
too harsh in my comments?
I like the compositions in all and the exposures are pretty good too, you haven't blown anything significant.
Do you shoot RAW or jpg?
Cheers,
