The Stairs
In most images we are unaware of perspective. It is present in most photographs though we take it for granted unless we see an extreme example such as single point perspective. This would be illustrated by the rail road tracks getting closer and closer together as they disappear into the distance.
The photograph mentioned in their e-mail that they like the image but felt there was something wrong with it that they could not put their finger on. At first I thought it was the colors. I played around with differ hews but could not get anything that appealed to me. Then it dawned on me “It’s not the colors, it’s the color”.
I might suggest to the photographer that they convert this to dynamic image to black and white. I have done a quick rendition below for your consideration.

Thanks Jim….I do like the contrasty B&W…it really made it more dramatic.

Very interesting and inspiring photo. I like both versions, with and without color. I think two other angles maybe interesting to see too. One lying down shooting from a very low angle and the other standing on a ladder almost with the high of the door looking down.

I think the color distracts for the graphics.

I think the colored version with its almost bluish tint to it has its own attractions just because of the color. Maybe by darkening the corners it could intensify the zoom in feeling. I think it would look good in a series of photos with the same color spectrum. But I also like the BW version because of its dramatic feel to it. It has the viewer look at the details in much different way. Both versions have their impact in different ways.
