Alpha legion - different scheme WIP

When I was at a forgeworld event I was talking to painter while I was there and he suggested this scheme for my alpha legion as it was the scheme they are using. So I thought I would do a few models to see how they compare to purpley blue that I wanted to use and I'm quite impressed with the look but not sure it's right for my pre heresy look, I think it looks abit more post heresy but great still.
