nice leading line. from the grain on the floor the focus is very good. i feel the picture is just missing something. maybe a figure passing by the entrance would help in my mind
I guess that it was quite dark inside and quite bright outside. Well done for getting lots of texture in the wood and retaining some details in the portion beyond the door.
Leading lines or curves generally have two purposes. One is to lead the viewer into the scene. The other is to lead you toward the main subject. It is most effective if they come in from the lower left because that is the natural direction humans visually scan a picture from so are easiest to pick up.
Nic leading lines begining at each corner. Makes for a good composition but it remains to be seen if the building directed to in the background makes a strong enough main subject to voters.
I like the photo but not what is at the other door. IMHO, I would have blurred that detail out, leaving a mystery as to what is at the end of the corridor.
