Is this an image from an airport ?
Reminds me a bit to it - kind of typical picture of a person in the wrong setting - a setting not really made for mankind - but machines - big ones obviously taking the huge space into account.
The image has a good impact - however - just a few thoughts about it - maybe you can make use of them when the next time in a situation like this.
The fact that the guy is walking out of the frame is a bit difficult - I guess most people would find the image more ''right'' when it would be the other way around. It also would make the picture stronger - because this impression of the huge contrast would be stronger.
Due to the construction - the elements you have a lot of lines in this image.
Lines are always easily picked up by the eye - and lead, guide the eye.
Thats the big thing with the diagonal line everyone is always referring too - a diagonal line guides through the image, creates dynamic etc.
You have many lines, almost separating the image into squares. Some squares with more content, some with less - and there is a risk that too much attention is kept at the right side.
I guess cropping a bit on the top – and a bit on the lower end would actually calm the image down, and bring more attention to your main subject.

Liker godt at han går ut av bildet. Den flukten sammen med den ulidelige heten han beskytter seg mot med ett tynt papir, gir meg assosiasjoner i retning av lidelse og lengsel.

Sola i senit.

Alle går vel egentlig rundt med en papirtynt lag av begreper mellom oss og evigheten.
Bra.
