yes - some really nice pics!
the one that caught me was the Pyramids one - very clever!
you obviously get out there and take photos and have an eye for a potential image. There are so many that it is difficult to comment on them. I would suggest that you go back to some of the locations, if possible, with a copy of your image. Think about what works and what doesn’t, and look at whether you could have gone in closer, taken a slightly different view point, perhaps down low or up high looking down, is there something that can be avoided or even made more of a feature, and see whether you get an image that really stands out. Let us see the results
