Hey Ingrid,
I also like your compositions a lot. The last one in particular, I find quite nice (the dog in the field). Please do not take this the wrong way. I think that you could use some work on your post processing though. Some simple PS tools, such as shadow/highlights and levels could turn these shots into real winners. I tweaked these in less than five minutes.
If you think they look improved, I will be glad to show you how it is done.
James
