For blood ravens, I choose codex space marines because it seemed like the most realistic option. I dont have the majority of these models so I would like to know if this army list is any good before actually getting them. If some parts could be tweaked or improved please tell me!

Im also not sure whether I should keep 10 sternguard or make them 5 and get 3 more bladeguards with an ancient or sum like that
