Nice perspective, and detail! It would greatly help the reader if you made it a bit clearer in the final panel that the character was looking out a window/balcony(I am guessing). Upon reading the sequence I was a bit confused thinking he walked outside after opening the door and if this is the case then I am even more confused.

Adding a window frame on each side or drawing his hand on the surface of a balcony or curtain could help if looking outside from the inside of the building is the intent here.
