Haha I'm glad you like them but I can't take credit for them, they are an asset I got off the UE4 marketplace: https://www.unrealengine.com/marketplace/en-US/item/3af095f1efd64795978624c8c1b6...
But I agree they are super cool. I'm a programmer so I usually end up picking up a bunch of assets to fill out my games, I'm terrible as visuals.
