"The Jabberwock, with eyes of flame..."

This year, I've been trying to buy a few less models by tidying up some of the more battered conversions and paint-jobs I did a while ago. A long time back, I made a small force of Grey Knights based on Alice in Wonderland (it seemed like a good idea at the time), which included a Jabberwock converted from the wreckage of a Chaos Defiler. 

There is quite a lot of description of the Jabberwock in Alice, but most of the words aren't in English, which doesn't help. However, there is this crazy picture by the original artist, Sir John Tenniel:

Not in any way nightmare-inducing

I went back over my own version, improved some of the painting and made it much more rusty. The head was built out of two leftover Tau hatches, and the wings came from a Dark Eldar skimmer. I seem to have decided against the waistcoat, though.

The base is a bit hard to make out, but he's partly standing on a chessboard with a red and white skull, to represent the red and white chessmen in the book (which I imagine he devours).

So, er, yeah. I do feel that something's slightly missing on him, but I'm not sure what. Any thoughts appreciated!
