Hi Sarah, catching up as best I can; if I've missed some of yours please let me know
Age; I like the first colour one best, which is a lovely shot. I think the rings get a little lost in B&W, and the composition is better than the single log.
Spread; obvious for the theme, but perfectly executed! I love the rustic feel of it, and its making me very hungry!
Together; nice shot, but it is a little blown in places. Certainly fits the theme though
Pack; I really like the first one. It is a shame about the sky, but hey, we have to take what we're given sometimes, and the composition and DoF are great. The second one is OK, but doesn't hold my interest the same.
Art; wow! My first reaction, for about 1/2 second, was "so what?", then it hit me what you've done with the PP, and it's brilliant! It's one of those shots that draws you in, so you find yourself staring at it far longer than you intended!
