Oh, that's perfect!
Since you have a very clear source of light in that scene, you can also use the shadows to generate perspective, if you don't like lines in the background for some reason.

(Not exactly like this maybe, but I hope get the idea)
Or you can just use both the line and the shadows and get something similar to this:

Whatever does it four you.
It's just a matter of adding something that creates detail and a bigger illusion of perspective, because everything else is pretty allright, and your drawing style is also very detailed and realistic, so it fits nicely imo.
