transfers are the last thing you need to finish off models, so I'd worry about getting everything else sorted first and making sure you're happy with the colours :)

the important thing is, as long as you tell your opponent what the weapon is, and as long as you are consistent with what models have what weapons, you're good

it looks like the majority of them have a bolt pistol and a chainsword, although a few have been mixed with other kits so you could really just call them whatever, power weapon etc. the one with the banner is an icon bearer. if you take a look online you might be able to match weapons

in terms of painting them, you can paint them any colours you like. black and gold is the "black legion" faction

there's a chaos cultist kill team but it requires a couple specialists, rules as written. you could do a legionaries kill team with the chaos space marines. rules are free on the kill team app, operative selection tells you what models you need. mostly kill team cares about wargear, their guns etc

mixture of chaos cultists and chaos space marines. the chunkier guys with the backpacks are space marines, the more ragtag ones with less armour are cultists

recently swapped out my scalpel to a new blade from a different manufacturer and it hasn't dulled nearly as fast as they usually do, resulting in three separate hand stabbing incidents in about a month

I think some people are trying to convince themselves more than anyone else

I wholeheartedly agree, and you shouldn't have to bachelor chow your way through it because it's 1000 years until they add flavour

add frozen berries and honey then some milk, put some good stuff on it and just use it as a base

diluting them slightly with normal bits definitely helps. these are my reavers so much more veteran and wild than the standard legionary, but I'll sprinkle cool stuff between the typical dudes too

Simpsons and Futurama are some of the best possible hobby background shows

I haven't listened to any AI music but I can almost guarantee that it's artifacting from fast fourier transforms. I have listened to more FFT processed audio than I care to admit and this is a good description of how it sounds if it's done poorly
