Besides asking your teacher, I'd say you need to read any material (what else does your paper say?) and maybe do some research on composition. If there's not a text book, are there maybe handouts or websites the teacher gave out? I'm not sure how you'd be expected to know all that without some reading materials.
My background is in education but infant/toddler development. What you quoted from the paper sounds like a lot to consider in one photo for critique. Of course I don't know what grade or class this is to know what you may have already been studying in class. If you're this lost you probably better talk to your teacher and find out what to do from here.
Meanwhile for this assignment you could look up 'elements of composition in art' and 'principles of composition in art' (and yes, I took all kinds of art all through school! lol). Search for it 'in art' rather than photography to get reliable information, otherwise it'll bring up sites by people selling videos and books, etc., or other info. that I've often found to be inaccurate and unreliable).
Edit - Searching that should bring up sites like The Getty museum, Kennedy (Center) Artsedge, etc.

If you want your photo critiqued, I'd say what I think you were going for was using lines and perspective. To me it worked in the upper part of the photo better than the lower part. If the cab was part of the picture, it needed to be in the frame or you needed to wait til it moved on. (If it was stopped, you could've changed your vantage point or your framing; you could've flipped the camera and shot it horizontally, but that would give you a totally different picture; if it was moving you might have been able to catch it in the frame but it takes practice to think and get a shot on the fly.) It has a bit of an odd angle so if you use that, think about how things work in the frame - do you want an odd edge of a red/orange door to the left? do you want trash cans/people? if so where should they be in the frame? Do you want the lean you got with the lens you used? Did that help or work against getting the buildings in the picture?
If you intended to show the interesting angle and perspective between the two buildings, I do see that so I think that shows in the photo. I think you made use of shape in the buildings. I think that gets 'lost' in the bottom part of the photo. Without the cab there you could've made better use of the white lines of the crosswalk and that pattern/texture to balance the height of the buildings. If you wanted to show the difference in size between the people and the buildings, the cab just makes for a big bright yellow distraction.
Get some help from your teacher and keep in mind that learning photography and getting good at composing and framing images takes time.
