Westminster Tube Station

Westminster tube station. Lights and concrete. Huge. It is impressive and has a very different architecture than other London's underground stations. It was my first trip there so I was caught unprepared, with my camera in my bag, but I managed to take two poor photos and after some work these are looking like above.

I am not a guru of photography either of photoshop and my skills on these are at a low level so any feedback is welcomed.
