The second is very nice, composition-wise, but I'm growing very bored of that blue digi-IR look, so I'm biased against it. It's no longer unconventional.
I happen to like the third the best. The lines are the most interesting, and it has a great range of textures. I think the color-casting is too heavy, though. I think a little desaturation would greatly improve it.
well thanks for commenting Max and admitting that you're biased , I wouldn't want you to be bored so I'm glad you found something that you like in these images. I did try different saturation levels on #3 and found I liked this one the best in the end.
