I like "Fire in the sky", beautiful, great angle, great light. I even like the blocky shadows to frame the scene.
"Clifford's tower" has (to my eyes) awful colours, dull grass which seems skewed too blue, ugly cyan sky, maybe improving those regions will let the ruddy sunlight on the stonework shine through. How about a bit less blue in the grass, more in the sky?
The first two look like thoughtless snaps, maybe there's more to them than meets the eye at first glance? Maybe the clock one when printed large will bring out the man looking up as a central focus. Maybe crop the black blob from the very top. Maybe crop leftmost geezer.
"Old house" : weakest one for me by far.
