Coming back after ages and wanted to see if my list is ok

Hey all, I decided to revive my old kraken list with the leviathan box and make my first 2000 pointer and wanted to see if I made any especially poor decisions/mistakes. Not looking to be super competitive just have some fun with my " I just think it's neat" list. I'm not married to the carnifex and it's load out so if anyone has a recommended switch I'd love to hear it. I can sub in 5 more genestealers if that's a good idea provided my opponent doesn't mind three mysteriously purple ones from one of my old kill teams. Id appreciate any advice as I've never been a heavy wargamer. Thanks.
