Getting into slaves to darkness and first list

So I already have belakor and I was thinking about getting into AOS with slaves to darkness. I dont really know yet how the list system works ( working on it ) and what units are needed compared to 40k from where i am coming after playing for a year. So i decided to make a list with units i personally like from their looks and some stats I have seen. I would be really glad if you could share your opinions on it !!!
