#1: The brick wall appears over-exposed to me, and therefore washed-out. Given that you were shooting with the full sun, the contrast is very high, and you have to decide whether the highlights or the shadows need to be preserved. If you have Lightroom or a similar photo-editing program, consider adjusting the curves to lower the brightness value on the high side. The sky could have been darkened with a polarizer. In terms of composition and framing, you have a lot of lines, but they all converge on a blank wall. The archway visible at the top of the image has promise, but it is not used effectively to frame the image. With this scene, you have to decide what the main focal point should be and then compose accordingly. As it is, there are many interesting elements, but they don't work together to make a compelling image.
#2: Better framing, but the right wall looks like it is falling in or at least leaning to the left. The reflected light is beautiful. The slight appearance of the wall at the left does not contribute to the image. I find the image somewhat soft, and would have loved to see more texture visible in the bricks to the right of the main doorway.
#3: Very nice detail. If there is a nit to pick, it would be to bring the hinge at the lower left slightly higher into the image.
#4: Nice tonality in the car and the background is suitably high-key. However, the horizon is tilted to the right, and the tree is growing out of the car's top. A somewhat better positioning would have been to place the tree a bit more to the left of the car so that the car is "sheltered" under the branch of the tree.
#5: Beautiful. Here, the bright sunlight on the ground is overexposed, and could be lowered by a stop or so, while the reflected light still being strong enough not to be too dark.
