Mega catch-up
Dangerous: Great idea and a lovely colourful shot. Should have had the more dangerous 5-rated jars at the front though!
Topical: Obviously no idea what it was about without reading the blurb, but it's topical to you. I realise you were exhausted and bent double but would a shallower DOF have made the legs stand out more?
Living World: Ha! Brilliant. Never thought about personifying a wordly object, what a great idea and what a fun shot.
Spiky: To echo other comments, good subject and not a bad shot but greater DOF and less pot would improve it. I took many (many) different shots of that shell and the inital ones all had shallow DOF, it was only when I increased it that I was happy.
