Didn’t you already upload an update of it with the suborbital cannon? Also as for realism, it’s fictional so I can’t say anything about that. Really most of the realism we’d have is things that are real life things (perhaps with slight modifications to allow a bit of that futurism, although keep in mind it’s only 5 years from nowadays) and for the most part things like tactics, doctrine etc. As for detail, it’s good. I may reccomend making it a bit smaller so that the small details are better visible (and maybe adding some anti air missiles and anti missile defense. Maybe all that artillery is not quite necessary. I’d make it about up to 150 meters long (a bit short if we’re talking star wars ships but about the size of a cruiser) unless aircraft are supposed to take off from it in which case it should be about 350m long. As for armament, the suborbital cannon is a good idea, but the 535 inch cannons (which is unrealistically huge as it’s about a kilometer i believe) and 155 inch cannons (which is also quite large at about 4000mm in caliber and the largest cannon ever made was a 917mm mortar so it’s also unrealistically huge) are unnecessary. The armament should consist of the suborbital cannon, a few 203mm cannons (203mm cuz it’s a real caliber used by the soviets and post soviet states) for close range bombardment when you don’t really need to delete an entire city with one hit, a bunch of anti aircraft and anti missile defenses (keep in mind you have a ginormous, absurdly large flying target and is gonna be a huge “shoot me” sign for any air defense system or even I’d say tactical/ ballistic missile systems so you want to make sure nothing hits it in the first palce since hiding that thing or dodging hits with it is gonna be impossible). This might also be able to carry bombs (since it’s huge anyway so maybe the engines will have enough power to lift the weight of another few tons of bombs and it’s also probably gonna be slow so bomb inaccuracy is not such a problem) as for looks maybe giving it a bit more sleek profile (by lowering the bridge section and extending it’s length). That’s gonna be it for my constrictive criticism (at least I’m trying to be constrictive with it and I hope I’m not to bossy or something). I reckon you should ask a few more users (preferably ones with a lot of stickfigure making experience) about this thing
