I recognise that first butterfly, or rather I have taken pictures of the same type. My better half knows what it is called so I'll ask her when she gets home later
Nice framing slightly of to the left hand side leaving space in front of the butterfly but as KenCo has said the bar in the background does slightly distract. It should be fairly simple to edit that out though if it bothers you much.
The second butterfly shot is very good. I like that one a lot
I also appreciated the sunset and can see why you have shot it with such a wonderful sky but personally the foreground is not defined enough to keep my attention/make the picture work. A leafless tree or a church spire would have been perfect to complete it IMO but mother nature is not known for hanging around for us photographers to get into position for our photos
Thanks for sharing.
