Gentlemen, start your engines

The sky was intentionally made whiter than the original to emphasize the vehicles at the bottom and also to make the image more dreamlike. IMO, a nice blue sky with fluffy clouds does not say dream.

On The High Steel

Once could totally miss the triangles in this shot since the framing leads the viewer to the horizon. If the horizon was placed inside one of the triangles then the triangle becomes a key part of the composition.

Triangular make-up

Comment:
The markings on the bird's face I believe is what you're referring to in your title however this is not a key element in the image. The triangle connection here is the framing of the bird (IMO). The two branches and the leaves across the top, though having objects poking into a composition from the edges usually detracts as they take the viewer out of an image.

Fill flash probably wasn't an option however more light and/or contrast is required to make the bird stand out better. Also, the tail is cut off so a not so tight crop would probably work better.

Nice idea to try for the not so literal approach to the challenge. The colour of the flowers are nice however the lighting is very flat. Fill flash may have helped. 5

Man Intersects Nature

Comment:
Yes, if I look hard enough I can find at least one triangle in the image however the main subject or composition does not say triangle to me.

edit: the composition is not working and I don't know what to suggest, maybe a wider angled shot to give more context.

Reflections

Comment:
I see two different compositions in this image. One using the symmetry of the railing and its reflection and the other with the railing, tree and bench.

For the latter, cropping most of the reflection and not cropping as much on top would make a very tranquil image. To exploit the symmetry a vertical composition might work better and I don't think the tree and bench are needed.

In either case, more contrast would probably increase the impact of the image. 6

Tree-angle

Comment:
The line of trees draws the viewer into the image nicely. However the overexposed areas are very distracting along with the lack of detail in the trees in the background.

Airborne Triangle

Comment:
Interesting idea to try and include the two parachutes and the person to form the trangle. To make it work better I think the colours of the parachutes need to be alot more vibrant so they stand out more and draw the viewers attention. Also, if they were a little closer to the person it might help as well.

Tropical Triangle

Yes they form a triangle however the overall image is not very compelling. It seems a little under exposed and a little too central.

Leading Limbs
by JesusfreakHBC

Comment:
Shooting up into a tree can produce an interesting shot. The line of the trunk here is a nice leading line. However, the image is rather small so the detail does not show very well. Also, the lighting is quite flat. A different angle of view may have helped to emphasize the triangle formed by the small branches near the top, maybe having the trunk enter the frame from the corner.
