my new Tyranid army

As you are probably aware I am starting up a new Tyranid army and I went out and bought the Battleforce not long ago. if you take a look at the images of my Tyranids you can check out the colour scheme, I think it is cool but I would like your advice to. I have only done a few models because, as you can see I have put a lot of time into each one, and I have just got the Battleforce literally a few weeks ago and I don't spend all my time painting Warhammer. so tell me what you think and I will listen to your advice and comments.
