honestly the only thing I can do to your CS is nitpick a couple things. For example, your character's name is Avernus, its a good name. Also happens to be the name of the crusade they the chapter is engaged in and the sector they are conquering. As I said it's minor and you don't have to change it, but it's kinda funny.

other than that, were you intending him to have been to be some sort of Vanguard veteran while in the Raven guard? if so than he should be a bit older than 150~. Or just a more regular assault sergeant, if so than he is perfectly fine. 

Other than those things it looks good. Great job, should be a fun character
