So, I've recently started collecting Chaos Space Marines.
- These are my first miniatures ever! - So yeah, I'm a newbie
I like planning things ahead, though. I want to make a Black Legion warband.
I plan to have Abaddon, his canonic lieutenants / captains (
those found in the Black Legion supplement) and a maybe a couple custom ones. So here's the thing:
1) Help me come up with ideas for modelling a few unique and cool looking lieutenants / lords for the Warband
2) Any idea on how to either make the Abaddon model look cooler / more unique, or maybe use a conversion for Abaddon?
3) Any suggestion for the Chosen chaos space marines? They'd be the retinues of said lieutenants and commanders

How to make them stand out and look cooler than your average space marine / cult space marine?
I have the green stuff and I am totally fine with kitbashing. I am not averse to spending money if the result will justify the expense.
Thank you a lot in advance.
