Low tech doesn`t come much lower :)
Good silhouette with some very nice background tones.
There seems to be a few of what look like compression artifacts..I hope it doesn`t affect your score too much....8
Nice! I like the use of the sillouette here, and the sunset and sky adds mood, but the barn/shed/whatever on the left is a distraction in sillouette form. I think it might have worked better with just the pulley device.
This is a nice composition. It is suffering from too much compression, this shows up as the noise along the lines. This also adds a bit of faint lines in the sky. When you save the photo it would help a lot to use a higher quality setting.
