From a "B" to an "A" ? ? ?

Ok, earlier this week I shared with you all a photo I took of a building as an assignment I had in my photo class I'm taking right now. Well, I ended up with a "B" as my grade because the teacher said it wasn't dark and dramatic enough, and it wasn't, especially considering it was supposed to be a dusk shot and mine looked more like it was taken in broad daylight! He knew I could do better and didn't want me to settle with just good. So, I went back and re-edited the photograph to what I think is a much better finished shot. I replaced the sky in the original photograph with a sky I had taken about two weeks ago just for the heck of it. Here's the before and after for you to check out. I was proud of the first shot, but now that I've taken it  to the next level, the second shot is far better. What do you think?

The lesson- only settle for your best and when you think you've done it, do better!!!
