Nice, angular shapes, might have been tempted to crop the bottom tighter as the light patch in the corner detracts from the rest of the image slightly. Cropping tighter would give it a more abstract feel too, hiding what the dark shape acually is.

the bottom, right corner might fair better if it were all black.

I very much like the geometry and composition of this.

However, it doesn't seem to me to have negative space. Although these are simple forms, I think they fill the frame quite completely.

I also think this could benefit from more contrast between the whites and the shadows. I think this could be a really powerful composition!

Nice angles and contrast.

This picture seems to be nothing but negative space, which in the long run in my opinion means it fails for this theme. Shouldn't the negative space be included to enhance the main subject matter? What is this shot about? I can't decide what I'm supposed to be focusing on.

I can see this shot being relevant in an "angles" theme or perhaps "architecture", but without a main subject it doesn't work for me in negative space.

Great shapes and nice abstract composition.

I like this image, but it appears to me to be some high-quality negative space in search of a subject...or did you intend it to be such?

why isn't this gorgeous piece featured?

Simple and effective.

Nice.
