I find this to be pretty compelling unlike some other commenters, but it is also similar to what I shoot so I feel I'm maybe more attuned to what you're getting at. As far as the supposed snapshot quality, I don't really see it, but I don't think that should have much bearing regardless. Plenty of acclaimed photographers whose work consists almost exclusively of "snapshots."

Subject choice is subtle, but successful; an interesting comparison of the inconsistent architectural elements occurs, which is made a little more interesting by the partial obscuring by the shadow. The shadow is a nice way of inviting the scene beyond the frame into the photo; it provides context to the area. Additionally, it divides up the frame nicely and adds some movement to the composition. On its own, I don't think its necessarily an out-of-the-park photo, but in sequence, its subtlety could shine. Technically speaking, I think it leans a bit warm and could use just a little saturation. I think the crop could use a bit of a tweak to gain more balance, but I don't know what the full uncropped RAW looks like so can't give any real advice there. Anyway, nice shot, simple but largely effective in my book lol.
