wow very interesting area to shoot! just some ideas i have by looking at these ( not sure what you are using to post process)
like the last one a lot, maybe a little darker would help the effect since lonely doesn't really equal a bright sunny day to me

or maybe if you have an edge darkening tool try that...and it could be straightened a bit , . you'd have to experiment with it some but maybe see if you can get the figure a little higher and a little more central (not in the center, just a tiny bit over)via cropping you'd see him more and i am guessing you want that to be the focal point? like you may be able to crop a little off the top? but imo don't crop to much since the wooden pole thing is interesting. it looks like you are going for a tiny figure/ big building to make the person more "insignificant" but he might be a little to unnoticeable due to the color similarities, maybe you could punch just his saturation up a tiny bit so you notice him more
i like the idea of the cart one but i think to much is going on in it, the bright shutter, the bright sign, the bottle tree thing, the tomatoes and cart plus the rustic brick, swhoo lots to look at! all very interesting but maybe a little too much all together so i wonder how it would be with some stuff cropped out. ie the cart and bottle tree thing and the shutter
or maybe the bottle thing, sign and tomatoes only? I'm very jealous over such spectacular photo subjects though!!

and i love the colors in this one, maybe a little more sat on just the tomatoes but love the blues
i might like the cat one more without the blue vase( even though it's really pretty and a great color), pretty much a perfect triangle that way and an odd number of objects as well....and the red wall is
very cool imo. that might need just a little darkening as well as the cat might be just a bare tad overexposed ( at least my monitor thinks so

)
interesting shots though, makes me wish i were there!
