Blood for the blood god

I am a student and don’t have spending money however I am very keen on playing age of Sigmar. For my birthday I was gifted 3 starter boxes. Daemons of khorne and khorne blood bound. I really want to expand though I do this as my hobby rather than drinking and partying. I really would like to get the judgements of khorne and a few blood thirsters so that I have a better chance at winning. I don’t play competitively but I would like to enter my first big tournament next year. Any help towards my goal would be hugely appreciated.
