A lovely set of images, really like the processing. There seems to be a trend of this type of processing on a few sets on here, the bold colours are there! but are ever so slightly toned down.
1. Love the pose and the completely obliterated creamy background, haven't got the foggiest what the background is. The bright green line to the left is slightly distracting and I must admit that I prefer idea of Lez325's crop, but like you said it needs to be the same ratio as originally took. So more dead space to the right to even the balance. It also appears to have a slight colour cast to it and tinge of bluey/green compared to No's 3,4 & 5.
2. Nice moment between your Mrs and your little lad. I like the closeness of the hand holding, makes me wonder what their thinking, looking out over the water.
3. Its all about the eyes. They are superb, look almost glass like and they really pop. The focus is spot on and dead sharp. The bright colour of her coat against the toned down muted background. Probably my favourite of the set.
4. I like how you've captured something so simple as a gate to lead you into the picture to the main focal point, very clever. I do however agree with an above comment that the big gate post to the left of the image is competing for space in the frame with your Mrs.
5. Nice, simple clean pose. Really causal looking. I'd like to have seen a bit more dead space to the right, I think that could have just added to the image.
Overall a nice set. What does the Mrs think of them? Is she a willing model for you?
