This is a nice attempt at a revamped training mission very strongly based off of the one from Thief 1.

Especially the areas in the beginning are quite pleasant to look at and could have stemmed from that original Training mission but the further you get along the more the style of the surroundings degrades and becomes boring, mundane and empty.
There's also some needlessly long filler sections between tutorial areas that are mostly just straight hallways or long stairways with nothing to look at or do. The different training areas could have been placed much closer to one another.

Even though I didn't need a tutorial to learn any of the mechanics shown here I'd say that this mission has some cool ideas for showing the player how to do different things. I liked the lockpicking tutorial in it's execution as a standout.
