Getting a catch-up on some comments!
Snappers Choice - Very interesting shadows. It's a bit busy and might benefit from being simplified.
Knob(s) - I had to zoom in to see you. Does it extend past the right or finish, if the latter I would prefer seeing the whole item.
You could "take your eye" out with those strings on the guitar head!
Letters - I prefer the colour version, it has more impact.
Kitchen - Interesting shadows from the fork with good detail on the prongs.
Broken - Nice textures, could see it being used as a background in a composite too.
Full - Great choice of the glass. Did you manage to fill it to the brim first time? Might benefit from a small crop at the right edge to remove the brighter area.
