A couple of quick pointers. The photos for the most part look good but you have some issues. Your B&W conversions add nothing, get rid of them. With super shallow depth of field, make sure your focus is on the eyes and not elsewhere. Your colours are inconsistent within the shoots, make sure they all look the same otherwise it will look off when put them in an album.
Finally, STAY OFF TRAIN TRACKS! The ones you’ve used are active tracks which means it is both trespassing and bloody dangerous.
