Chain of gold

Too many divergent leading lines. My eyes keep darting left and right, up and down. Nice concept, but the composition needs to be cleaned up a bit.

79 Aurum

Go on, crop in! Let the lines fill the frame! The border on top of the white border just shrinks the subject here too much. The square crop works with this shot, but it's just too loose.

With a faster shutter speed you may be able to avoid the motion blur on the bottom flower. Or you could use a stake and twist-tie if it's windy.

I had to do a little research when I saw this. A beautiful, symbolic, and historic image. Well composed. One technical note, the focus seems just a tiny bit off here, it pulls the eye too far to the left.

Comment:
Aluminum is nice and all, but I'm not sure it gets me that excited. I like the muted colors in this shot. Tone mapped?

This is a really interesting photo, but to be honest, I can't really tell what's going on. I would expect to see this with a caption, but it is intriguing.

Nice texture! Perhaps a bit to wide a view, I'd like to be able to see more detail.

Hydrogen - Dominant Element in the Universe
by Pascal

Comment:
I have no idea how to critique astrophotography. It's like trying to find fault with the universe itself, a futile endeavor indeed. As an abstract, however... The centered composition with so much negative space diminishes the impact of the central subject. It almost feels too clinical, too sterile. A closer crop, or off center comp, would do a lot here.
