I really like the images, but not the processing. The first one is too saturated - to me an old shed should look rusty and run down which clashes with the "youthful" vibrance you've given it. The others are all a bit orange/yellow which makes me wonder if your white balance was out.
Of course if this was your intent then that's your choice (you are the artist after all) and you can ignore these comments (plus ee my tagline below

)
Discounting my comments about processing the standout for me is the third image since there is so much lovely detail for the eyes to feast on
