Hi guys, I'm a programmer by training but I'm a big fan of pixel art too. After spending close to 10 hours of staring at photoshop and painting one pixel at a time, I've successfully completed a complete wall tileset, with all joints (cross, T-junctions, L-shoulders, variants, etc).
Here's how it looks like:

Comments and criticisms are welcomed! Don't hold back just because this is my maiden attempt at tile art!
EDIT:
Added revisions after comments:
New background tiles:

Changed shadow to 60% opacity and blend mode to "Overlay"

Added 1px grey line to the bottom of the wall

EDIT:
In-game wall randomizer:
