My first impression of this work: this is GREAT.
My second impression, which included realizing Gollum is climbing down the left side: oh, this is AWESOME.
Gollum is the best thing about this piece. Not only is he very well-drawn, but the way he's drawn reflects his character: sneaky, resentful, unexpected. I almost wet myself when I saw him. XD
And I just now noticed the Watcher's tentacle. This piece is going to be the death of me.
