I've created a more pragmatic and minimalistic character sheet from my experience in games. I recommend printing it on to two separate sheets of A4 paper (the backs of pages are good for buying xp or keeping campaign notes). Here's the link:

Here are the changes:
No background! Save on printer ink!
The two pages are divided into a combat page and general roleplay page
There's a specific section for you to put your weapon training talents (probably a little bit large, but there should be a place).
Anyway, this is extremely bare bones, and any changes or suggestions would be welcome. I may add on a separate psyker page, as psychic powers play significantly differently from the rest of the game.
