I'm not a big fan of "make-your own rules" lists, so my review isn't going to be terribly detailed, but one thing strikes me as a terrible mistake: the inclusion of Chosen, without them being basic Terminators.
Regular chosen are fairly poor. With their only defining traits being their larger amount of heavy weapons and the ability to take Special Icons, they're a pretty poor choice to start with...
..And
then people decide to make units of aspiring champions...
The Aspiring Champion unit is by far the biggest recurring mistake I see in army lists. The unit consists of very few models and takes up around a quarter of your army. Not only that, but your unit in particular is one of the more poorly composed AC units I've seen (I'm not trying to be insulting, I'm trying to
help, especially since you're a newer player). Minor Psychic powers, to be frank, just suck, and inferno bolts are one of the most overpriced upgrades for ACs, especially with pistols. Adding Furious Charge and Power Weapons just further adds to the expense and ideal versatility of the unit, but I guarantee that any player who knows what they're doing will shoot that unit down in a turn, easily. It's 5 models that are all just as easily killed as a regular Chaos Space marine.
While having a single unit like that as your HQ can be fine (minus the minor power he's got and furious charge and plus Daemonic Aura), an entire unit of them is one of the worst army composition decisions you can make. I highly recommend against it. You'll occasionally get newer players telling you that their AC units are great because they "get 25 S6 I5 powerweapon attacks on the charge!" (Mark of Khorne, Daemonic Strength, Mutation, Power Weapon and Furious Charge), but in reality that unit will never make it into close combat, much less get even one or two models into base contact with their enemies. I find it hard to fathom a player dumb enough
not to shoot at the unit, but said chaos players don't seem to understand that, nor do they feel very good when they actually field their 'super'-unit.
Anyway, as said, I'm not making a big review of the whole list, I just wanted to make a big point of how poor chosen aspiring champion units are. Chosen as Terminators (though not Terminator ACs) are a good buy, with good versatility, deep strike, killing power, the ability to take chainfists and reaper autocannons.. all of the good stuff. Chosen Aspiring champion units lack resilience and effectiveness, and cost way too much to boot. I suggest that they be immediately removed, for your sake.
