Hi Dave,
Looks like quite a catch up from me is in order here... Here goes...
Building - I have to agree with
@Allan.H, whilst you've achieved a colour pop on those buildings it is jarring. That said, the red door on the church is jarring even in the full colour photo. What on earth possessed them to do that (geddit). You did colour pop on week 30, the Free Week, it was the watch and worked so much better in that context.
Empty - Both work well, I think I prefer #2, for the colours involved.
Plastic - In your comfort zone with these 2 shots

I think Emily is fractionally my preference, I think as there is less distraction in the background.
Interior - Quite a riot of colour going on in this one too. Could you have gotten a step to your left maybe?
Life - #2 for me. Nicely captured.
Free Week - As per above, this works really well with the colour pop technique. I think the re-edit for me.
Closed - He certainly seems engrossed in the music. I don't mind the high ISO look, noisy is better than blurred.
Wide - The mermaid for me. It reminds me of cosplay.
Dirty - Such a shame that it's just been abandoned like that. But perfect for the theme.
Drink - Using the 90 like that has certainly allowed you to completely loose the background. Nicely done.
Full - Abi is the shot of the 2. The flower seems oof to me
