Pros:

Its Shepard fully animated with the first person arms!

Cons:

I play with the highest possible gfx available and for some unknown reason Shepard looks like a silver toy and rather un-detailed. This is a weird bug and a rather irritating one. Fix this and the model should be just fine!

Conclusion:

Aside from the bug mentioned above the skin is just fine!

Pros:

The Dark atmosphere really makes things more interesting.
On Realism Expert things get a lot harder when you cant see all items even nearly as easily.
The randomized paths makes it interesting and fun to play again and again.
The graveyard in particular looks awesome though I think you should add more mist effects to make it creepier.

Cons:

Some areas are too dark particularly when playing on Realism Expert as you are being pressed from all sides and its too dark to see in front of you, a prime example of this would be Chapter 2 where you take the left pathway to get across the park the terrace there has no lightning and it makes things a lot more of a pain in the ass the it should be. The added difficulty by removing those med kits is not bad but you should consider adding more pipe bomb/Molotov/Bile placements since the Crescendo is horrible if you only have pills and adrenaline available.

Conclusion:

Its fun, darker and overall better to the original (in my opinion) but it needs a bit more tweaking.
