Waiting for the transformation to start

So I decided to draw Werewolf Henry Green getting prepared to transform.

Here's the idea I thought behind it:
For a while Henry Green couldn't get out of the city and to the woods when the full moon rises which then causes a massacure on the streets from the wolf but when the Frye twins came around, They (and a couple of associates) were able to find Henry Green a spot underground of London. The Chains are made of silver, one of a werewolf's weaknesses, to keep wolf from escaping.

I know this doesn't look like the underground from the game but I tried.

I also had an idea to put missltoe arround the place as well (I'm sure Doctor Who fans would understand) but I wasn't sure it would work. what do you think, should he have it in the area with him?

I made 2 other versions as well:
