I like these though I'm not over keen on the faux purple in the sky. With that lovely orange there, I don't think it needs it. But I entirely admit that is just a matter of personal taste so can understand that others might like it and as I say, it does make a good picture. The shot itself is lovely.
The silhouette against the man thing is fun but for my taste a touch contrived. We've all done the silhouette against the moon thing at some point, I know I have and not getting as good as result as yours! It does look good and actually probably the only people who will see it as I do is people on here who have done it themselves. Show it to a non-photographer and they'll love so it just shows we are often too critical for our own good LOL.
I love the results simply as pictures anyway, very nice work
Cheers,
Rob
