The bird feels a little dark to me, although it could be the monitor I'm using. The depth of field however is beautiful on this picture.
I've got this weird thing about cutting body parts off of people and animals and otherwise cutting things off by bits, but I think it's really just a me thing so I shouldn't bug about it. I've got weird things about bulls-eyeing subjects too, but again that's just me.
The alleyway feels a bit plain to me. Maybe if you shifted over a bit so everything was nice and centered and symmetrical and the light was a bit more interesting. Like sunset or sunrise. A little more directional, a little more warm.
Pretty flowers, though you've got a bare patch right in the foreground.
The coastline is beautiful too. I'd crop it down a bit so there wasn't quite so much sky. It keeps trying to draw my eye even though it's not the main focus.
Feel free to totally delete this if you want. I like to yammer about what I think of stuff sometimes. sweatdrop
