kesey i do a bit of photography and i really like your escalator photo
pity you couldn't have centred it more but i can see that you went for the centre of the escalator so had to compromise - but cropping the photo would have solved that
don't ever worry about cropping a photo or enhancing it in post production as you're making a piece of art and not just an everyday snapshot as any old joe can do that
composition is the be all and end all of good photography - never just turn up at a location or an opportunity and take one photo and think 'got that - next!'
explore the scene - play with the composition to find another angle or view
and don't do what most people do and that is stand up with your camera/phone at arms length - you might get a good composition like that but try squatting or sitting or lying flat or even stand up on something to find another interesting viewpoint
the great thing is is that you are looking - you're seeing things that you want to photograph and that's how you learn and become a better photographer
your photo is crisp and sharp, which an architectural photo should be, has nice colour-balance and is interesting - that's a big thing, you could take a sharp well composed photo of a scene but it's just boring, here you've made the viewer interested - and how interesting actually is an escalator? ha ha but the leading lines and the symmetry drag you in to its 'story'
now whether the photo would be better without the person in it is down to personal preference - some people like it some don't
it's slightly 'blown out' at the top but by taking a number of photos of the same scene using different settings would mean that you could of had that at the correct exposure too - and overlaid it in post production
again, some people might prefer that it's brighter at the top but that's all down to you as the photographer to convey what you want to say
just keep taking photos mate
