A quick catch-up from me as I haven't been around for a few weeks, and you've added some great images! The smoke images are all really good - full of impact and a sense of movement - but my favourite is the first, with the super swirls at the top and the way the whole thing is contained within the frame. The strong contrast between black and white helps to bring out the details, too. Something I've never tried and really must
The peacock feathers are a great idea for Vivid and spot on with all those intense colours, the folly is perfect for Large with the way it towers above the ground and points into the sky, with the warm light a real bonus, while the interior shot at Bluewater is a super architectural shot and full of great details and tones. Finally, you found a perfect subject for the re-shoot of Structure, full of fascinating natural details, and I like your choice of a tight close-up and the side-lighting, which is very effective.
