Congratulations on the HM Wendy. I remember that week being a great one for sunsets with the particularly lovely hues you captured here. The similarity to Robert's is quite amazing.
I do like this shot (I'm a fan of sillhouetted sunset pics), although I'd have loved to see the colours of the sky pop more so I'd have pushed the saturation of the red and yellow channels up a bit. Their poses are a little bit stiff and obviously posed, I feel a more relaxed posture would have been a bit better. Overall it conveys a nice idea of a united family sharing a nice moment, a thoughtful shot and good composition/exposure.
I am a little torn on this photo, I like their sharp silhouette but I almost would rather the clouds have full focus and the silhouettes be slightly blurred. Great shot tho.
