You'd be better to show an overlay that has full vision of the paths rather than roof textures to make paths clearer, as you still missed the route under bombsite B.
Yes Fnuggi usually wrecks everyone and it's not hard to plant a bomb when everyone is dead (in fact I remember one bomb plant when I was CT because I couldn't get to it in time as I had to follow a weaving route which didn't take me to the bombsite). but that doesn't change how imbalanced the CT defense was. As you can quite clearly see from your pathing, CTs have a wealth of movement and T's have very little scope for rotation.
Think about the scenario that Ts are trapped outside A, and want to rotate to B asap. They either run via the underground mid are where CTs can quite clearly see them if they haven't already pushed or they run via T spawn. That rotation time is absolutely awful.
Don't get me wrong, I love the detailing you've been doing, but you should really hold horses on it and fix your layout.
Good luck.
