I would have either centered the building or angled it more. As it is it’s kinda lost…. The white of the clouds I would cover with the building to minimize it and accent the blue sky. I would have taken the shot when the entire building was lit better, the shadows behind the stairs are nice, the bottom half of the building is dull as is. The small piece of structure in the bottom left should be removed or shadowed. I would also like more definition in the entire building, sharper with more defined edges.
My opinions may or may not be better, I am not a professional, my observations are merely what catches my eye that would improve the photo for my taste. My tastes are a lot of the time a long way from the beaten path though…
In the digital age, photography is a blast, it was fun before, now it’s a riot. Take lots and have a ball.
What do you have for equipment? Are you versed with Photoshop or Paint Shop Pro? I love the post editing, you can do most anything other than save a blown out or totally black image.
