Pros:

Feels like a fitting replacement.

Includes a new replacement for the incapped GUI image (the one that usually sticks out the most).

Cons:

Doesn't add much.

Doesn't replace his face on the health GUI (I'm using the default menu).

Conclusion:

While this doesn't add much to him, it's a good example that simpler things can be better than larger projects. When you use it, you feel like Ellis has a new believable backstory, which doesn't change the game at all- but at least it feels realistic enough to make you believe he was a construction worker, rather than just replacing him in general... if you catch my drift.
