Hi Susie - can't keep me at bay for long, I'm afraid
Old - great colours in that first pic. Definitely looks like it's in need of the dry dock (or the scrapyard)!
Metal - super composition for me and I like the low key lighting. Focus is a tough one on this - I can see why you wanted narrow DOF, but I might have rotated the pen slightly so it's all in the same focal plane, allowing the tip and writing to be sharp? The lid could still be OOF as you have it. (Or a smaller aperture, of course!)
Captive - funny and the note is a great touch. Not so keen on the lighting if I'm honest - I know it's the look you wanted, but it just feels as if it could do with a good stop more exposure for me. Of course, then you might be blowing out his right foot and the knife blade. Great thinking for it though and in the circumstances, good to get a shot and great to get a funny one

Miniature - last one for me and although I'm not often a big fan of T&S, it works well with the highly saturated processing to give it a proper "toyland" feel. Very very cleverly done for me as it takes what would be a "regular" photo and makes it really work in the context of the theme. Smart Susie!
Happy - love the montage of Archie. Wonderful flattering natural light and boy does he look happy! Great job.
