Hey Colin - welcome back mate
Already behind with yours... so trying to multi-quote and comment on photo posts only to catch up, only to find you don't host them off site, so I have to open two tabs and flick between the two Grrrrrrrrrr
Spiral - For me it's the signpost, a lovely acute angle, although the snail shot I like, I'd have cropped it more to take out the dark patch and by that knocking out of dead centre frame, good focus on it and well lit anyway
Silhouette - Apart from the sea sloping down hill I like this one, the figure is well silhouetted, there is a nice glimpse of light reflecting off the head, and the sun rays and lens flare add a real nice element to me
Animal - Awwweeee bless
really like the reflection on this one, it appears to me looking down at itself, nice image
Medicine - 3 Great images - liking each for their own reasons, the first I like the overhead PoV, the second I like the simplicity of the shot and the way the tablets fade into the distance, but the third is the winnwer for me, similar to the second but with much more interest, nice low angle again, nice high key image but the colour of the pot and lid make this shot for me, nice one
Proverb - Well... theme wise dead on and a good idea, but sorry technically it's all over the shop, my OCD wants it straightened, the coins heads aligned, the lighting more even and the blacks upped to remove some of the background wrinkles, don't get me wrong, love the idea still and the touches like the copper coin are good
The second one works much better for me, the focus is just right and I'm liking the sepia type colour of an old looking book
