That's not an extreme transformation in the least. It looks like two years of solid, modest gains. You do look good, not knocking that. But it's the furthest thing away from extreme.
You made great progress with your legs, but as far as your upper body is concerned you just threw your chest way up in the air like a douche bag. Pose like you did in your first photos - the correct way. You know how to do it.
Good progress.
