Thats a really cool piece, but I feel as though it doesn't live up to your otherwork, which is being displayed. I think that it's a good sig, but the render and background dont merge well because of colours, you need a light and fairyish render to be able to work with the space element I think. Unless the space was a bit darker, to sooth out the colours of the render. I like the text alot though, it sets the mood for the piece completely.
